The force required to accelerate an object depends on the object's mass.
Newton's second law states that Force = Mass * Acceleration. Re-written to solve for acceleration, this becomes Acceleration = Force/Mass.
Basically, this means that the more mass an object has, the more force is required to accelerate it. Also, the faster you want to accelerate the object, the more force you will need.

What force would help you slide down a slide?
Gravity? the strength of the floor?
What is glass slide in microscope?
A microscope slide is a thin flat piece of glass, used to hold objects for examination . Typically the object is placed or secured between the slide and a cover slip
The force of friction is directed opposite of the way an object is moving because?
The force of friction is NOT ALWAYS directed opposite the direction an object is moving. Consider, for example, an object (like a book) resting on a piece of paper on a table. If you gently pull the paper and the book moves with the paper, friction between the paper and the book is causing the book to move in the same direction as the paper. Even if you pull a bit faster and the book slides in the same direction as the paper motion, but a little bit slower, the friction is the force which is pulling the book along--in the same direction of the paper motion.The direction friction is acting is opposite the direction of the relative SLIDING or attempted sliding of surfaces. In the cases above, without friction, the book would slide opposite the direction of paper motion, so the friction is in the same direction, accelerating the book along with the paper. In the first case, the book's acceleration is the same as the paper's; in the second, the book's acceleration is less than the paper's causing the book to actually slide backwards relative to the paper's motion.
How does weight effect the momentum of a moving object?
Strictly speaking weight is the force of gravity acting on an object. It should not be confused with the objects mass. Weight ⇔ force When something is on the moon it weights less but its mass is the same. Something special about gravity is that in the absence of air friction, all objects accelerate down at the same rate irrespective of their weight because as a objects weight increases, so does its mass. Take the equation.. F = ma or (weight of an object) = (its mass) x (its acceleration) When an objects weight doubles so does it mass, so the acceleration does not change.
What would it be like without friction to pick up a pencil?
The pencil would just slide out of your hand because there would be nothing holding it there. You would have to balance the pencil on your hand!
If the friction equals the force why the object moves. why it doesn't stop?
Friction force is equal to the force applied only when the object is not moving or it is just beginning to slide. Once the object has started motion completely, it means that the force applied has exceeded the frictional force
If you exert a horizontal force of 600N to slide an object across the floor at a constant speed is the force of friction between the object and the floor greater than less than or equal to 600N?
Since the object is moving at a constant speed, the net force on it must be zero.If I'm applying a constant horizontal force, then the frictional force must be equal to my force = 600N and in the opposite direction to my force.
What force makes a car begin to move?
1. The forces involved are arise in response to the action of an applied force. 2. Discuss the interaction between an object and a surface it is resting on; the object pushes down on the surface; the surface pushes up on the object with an equal force; this is called the reaction of the surface. 3. Discuss the interaction between two surfaces which slide (or tend to slide) relative to each other; each surface experiences a force in the direction which prevents (or tends to prevent) relative movement; this interaction is called friction.
What force pulls an object down a slide?
when you're going on a slide you are being pulled toward the ground so it would be gravity.
How do you make an experiment with the question How does the weight of an object affect the force needed to slide the object?
You try it! You use objects of various weights. You measure the force in each case. You look for a pattern in the results.
Are you agree that your weight is equivalent to the friction force. Why?
No. On a horizontal surface the normal force is equal to weight. If you are moving at constant velocity you only overcome frictional force, which is not equal to weight. This is easier to see on an incline. At some point an object will slide at constant velocity down the incline. This is related to trig functions of the angle of incline multiplied by the weight which is always less than the weight.
How is the motion of an object affected when a force act on it?
According to Newton, it accelerates (Force = mass x acceleration). But beware, the force is the net (total) force, not just what you apply. For example when you hold a heavy object you are supplying a considerable force. But gravity is pulling in the opposite direction so the total force is zero. Similarly, if you try to slide a heavy object along a road, if you cannot overcome the limiting frictional force, nothing will happen.
If matter moves a force acted on it?
Matter is held down by the force of gravity, like a cup placed on a tabletop. The cup needs either for the table to be tilted, allowing gravity to cause the cup to overcome the force of friction and to slide off the table, or someone needs to push (force) the cup sideways.
What things can cause friction to loose its force?
The resistance to movement between 2 surfaces which touch each other, is referred to as frictional force. This frictional force will be reduced if any or all of the following things happen. 1. Make the surfaces rough and things will not slide over each other so easily because the frictional force will be greater. 2. Choose a different material for the surface, which has a very slippery nature. 3. Choose a more slippery surface on the moving surface of the object. The ' slipperiness' of the materials is referred to as the 'co-efficient of friction'. The force needed to overcome the grip of friction, is always a fraction of the weight of the object but in rare circumstances with rough surfaces, the grip of the frictional force can be equal to the the weight of the sliding object. If a slope is equal to, or steeper than 45 degrees, then the object will always slide down this incline without any need to push it.
What are the example of static friction?
Having your hands touch. Anything where things aren't moving, they are just touching. If you are asking about Coulomb Friction, static friction is the resistance to movement (sliding) of one object over another when force is applied but there is no movement. Once the objects begin to move in relationship to each other (slide) the force required is lessened and dynamic friction is in play. Static friction requires a greater force to get an object moving, dynamic friction requires a lesser force to keep the object moving.

What is an unbalanced fprce?
An unbalance force is one that is not opposed by an equal and opposite force operating directly against the force. Examples of unbalanced force are when you kick a ball, or slide furniture across the floor.
