A car is driven up a hill at a constant speed Discuss all the forces acting on the car What pushes it up in the hill?
The forces acting on the car include:
1) Weight (mass x gravity) of the car.
2) Normal force between the inclined plane at each tire (perpendicular to the inclined plane).
3) Force of static (rolling) friction acting between the tires and the inclined plane (parallel to the plane and acting against the direction of rotation of the tires).
4) Force exerted by the car on the plane (parallel and opposing friction on the inclined plane).
5) Drag force depending on air resistance and velocity of the car.
The car is allowed to climb the hill because of the static friction opposing the force it is exerting. Without this friction, it would not be able to climb the hill.

What is the resulting motion of forces acting on a unbalanced bicycle?
Constant acceleration is the resulting motion of forces acting on an unbalanced bicycle.
What do you know about the forces acting on an object that is moving at a constant velocity?
When an object is moving at a constant velocity, the forces acting on it are balanced. This means that the net force on the object is zero, which allows it to continue moving at a constant speed in a straight line. The forces acting on the object may include friction, air resistance, and any applied forces.
Can a body in equilibrium if it is in motion?
It can be in equilibrium if in constant motion (constant velocity) as no forces are acting on it (no acceleration)
When the forces acting on an object are balanced the motion of the object?
When the forces acting on an object are balanced, the object will remain at rest or continue to move at a constant velocity in a straight line. This is known as equilibrium.
What are the similarities between balanced and unbalanced forces?
An object with balanced forces acting on it is still. An object with unbalanced forces acting on them moves at an non constant velocity. It is possible for an object to have balanced forces acting on it and yet move in a vacuum.
Can an object be moving at a constant speed if three forces are acting on the object?
Yes, an object can move at a constant speed if the three forces acting on it are balanced, resulting in zero net force. The forces can cancel out each other's effects, allowing the object to maintain a constant speed.
What will happen to an object moving at a constant speed if the forces acting on it are balanced?
If the forces acting on an object are balanced and the object is moving at a constant speed, the object will continue to move at that constant speed in a straight line. There will be no change in the object's velocity or direction of motion.
Are there any balanced forces acting on the freezer if so what are they?
Yes, if a freezer is at a constant velocity or stationary, there are balanced forces acting on it. Typically, these forces include the gravitational force acting downward and the normal force acting upward from the surface on which the freezer rests.
Can an object in free fall has a constant momentum?
Yes, an object in free fall can have a constant momentum if no external forces are acting on it. In free fall, the only force acting on the object is gravity, which causes a constant acceleration. As long as no external forces are present, the momentum of the object will remain constant.
Does an object moving in a constant speed in a straight line have any forces acting on it?
It will have zero force BUT, it WILL have a constant velocity
What are the between balanced force and unbalanced force?
An object with balanced forces acting on it is still. An object with unbalanced forces acting on them moves at an non constant velocity. It is possible for an object to have balanced forces acting on it and yet move in a vacuum.
Is it possible for a car moving with a constant velocity to have forces acting on it?
No,because if the car is moving at a constant velocity that means the acceleration is zero. So the net force is zero and there may be some forces acting on it. Only gravity, downward.
