What else can I help you with?
Without air resistance all objects regardless of their size and mass exp erience the same acceleration of gravity is it true or false?
True. In the absence of air resistance, all objects near the surface of the Earth experience the same acceleration due to gravity, which is approximately 9.81 m/s^2. This means that regardless of an object's size or mass, they will fall at the same rate in a vacuum.
Is it possible to experience centripetal acceleration but not tangential acceleration?
Yes, it is possible to experience centripetal acceleration without tangential acceleration. Centripetal acceleration is the acceleration directed towards the center of a circular path, while tangential acceleration is the acceleration along the direction of motion. In cases where an object is moving in a circular path at a constant speed, there is centripetal acceleration but no tangential acceleration.
In freefall do all objects near Earth's surface have the same acceleration?
Without atmospheric drag, all free falling objects near earth's surface will have the same acceleration. But because of friction with the air (air resistance), the velocity of objects due to that acceleration is limited. The actual velocity is dependent on the surface area of the object relative to its mass. The principle of the parachute is to increase the surface area of a falling object with respect to its mass.
Neglection air resistanceabnody falling freely near the earth surface?
Neglecting air resistance, a body falling freely near the earth's surface falls with an acceleration of 9.8 meters (32.2 feet) per second per second, regardless of how big, small, light, or heavy it is.
Can anything ever have a downward acceleration greater than g?
Yes, objects can accelerate at a rate greater than "g". Most objects, when falling in the absense of air resisitance, accelerate at a uniform rate of -9.81 m/s^2 (this is under ideal conditions on Earth). Air resistance tends to decrease that acceleration. The classic example of greater than "g" acceleration is a bungee jumper.

Why don't all objects fall to the earth at the same velocity even though the acceleration?
The acceleration is the same for all objects, as long as air resistance is insignificant. After a while, different objects will have different amount of air resistance. Also, even without air resistance, the speed depends not only on the acceleration, but also on how how long the objects are falling.

How does an object affect its accelration during free fall?
Without propellers, jets, or a parachute, an object can't to anything to affect its acceleration when it's falling. "Free fall" means moving under the influence of gravity only, with not even any air resistance. In that situation, on or near the surface of the Earth, acceleration is constant, regardless of the size, shape, mass, weight, or gender of the falling object. That number is 9.8 meters (32.2 feet) per second2 ... known as the acceleration of gravity on Earth.
What is the opposite of resistance?
The opposite of resistance (opposition) could be cooperation, or acquiescence, or surrender. The opposite of resistance (electrical) could be conductance.
What can you do to accelerate an object faster if you can not increase the force?
To accelerate an object faster without increasing the force, you can reduce the object's mass. This would allow the same force to produce a greater acceleration according to Newton's second law, F = ma. By decreasing the mass, the object will experience a larger acceleration for the given force, resulting in faster acceleration.
A projectile moves in a parabolic path without air resistance is there any point at which acceleration is parallel to velocity?
Yes, the acceleration is parallel to the velocity at the highest point of the projectile's path, known as the apex or vertex. At this point, the velocity is momentarily zero and changing in direction, while the acceleration due to gravity still acts vertically downward.
Is it possible for a lighter object to fall faster than a heavy object?
Not without the help of air resistance. With plenty of air resistance, a small, light, wadded-up sheet of paper could fall faster than a big, heavy sheet of lead foil. In the absence of air resistance, the size, age, weight, mass, shape, race, creed, color, religion, political persuasion, gender, or national origin of the object has no effect on how it falls. They all fall with exactly the same acceleration, and all reach the same speed in the same amount of time.
Why does a bowling ball move without acceleration when it rolls along a alley?
Strictly speaking, it moves with negative acceleration. The forces of friction and air resistance both act to slow the ball down. If the lane were long enough, the ball would eventually come to a complete stop.
