How does an object get its gravitational potential energy?
An object gains gravitational potential energy when it is lifted against the force of gravity. The amount of potential energy an object has depends on its height above a reference point, typically the ground. The higher the object is lifted, the greater its gravitational potential energy.
Which force is often associated with an object's potential energy?
Gravitational force is often associated with an object's potential energy. The potential energy of an object is related to its position in a gravitational field, and the force of gravity acting on the object determines how much potential energy it has.
What is the force that acts against gravity?
The force that acts against gravity is called the normal force. It is exerted by a surface supporting an object, pushing upwards to prevent the object from falling due to gravity.
What is the force that supports an object against gravity?
The force that supports an object against gravity is called the normal force. It is exerted by a surface to prevent objects from falling through it. The normal force equals the force of gravity acting on the object.
How can potential energy be changed by gravity?
Potential energy can be changed by gravity when an object is lifted or lowered in a gravitational field. Moving an object against gravity increases its potential energy, while moving it with gravity decreases its potential energy. The gravitational force acting on the object determines the amount of potential energy it possesses.

What is the amount of force required to lift an object against the force of gravity equal to?
The acceleration due to gravity (9.8 meters/sec.^2) * mass of object.
How is gravity used for energy?
When pushing something up against the force of gravity, you are making an "energy investment", so to speak. (You require energy to push the object up; this energy can be recovered when the object falls back down.)
Work done in lifting and lowering an object?
The work done in lifting an object is positive, as energy is input to move it against gravity. The work done in lowering an object is negative, as the object is moving in the direction of the force of gravity, and energy is being released. Overall, the work done will depend on the distance the object is lifted or lowered and the force applied.
How does the force of gravity affect the energy of an object in motion?
The force of gravity affects the energy of an object in motion by either increasing or decreasing its potential and kinetic energy. Gravity can either pull the object down, increasing its kinetic energy, or lift it up, increasing its potential energy.
What is the minimum force to go against gravity?
The minimum force needed to go against gravity is equal to the force of gravity acting on the object, which is the object's weight. This force can be calculated using the formula F = m*g, where F is the force, m is the mass of the object, and g is the acceleration due to gravity (approximately 9.8 m/s^2 on Earth).
How does an object gain potential energy?
An object gains potential energy when work is done to move it against a force, such as gravity or a spring, creating a separation between the object and the force acting upon it. This stored energy can be released as kinetic energy when the object is allowed to move back to its original position.
Why when you push an object across a desk the work done is not equal to the change in gravitational potential energy?
In this case, you are not doing work against the force of gravity, but against the force of friction.
