Forces and Transformation REVIEW

Front

What is kinetic energy?

Back

Kinetic energy is the energy an object possesses due to its motion. It depends on the mass of the object and its velocity.

Front

What is potential energy?

Back

Potential energy is the stored energy in an object due to its position or state. It can be gravitational, elastic, or chemical.

Front

What happens to energy when an object moves from a higher position to a lower position?

Back

The potential energy decreases while kinetic energy increases, keeping the total mechanical energy constant.

Front

What is the principle of conservation of energy?

Back

The principle states that energy cannot be created or destroyed, only transformed from one form to another.

Front

What is elastic potential energy?

Back

Elastic potential energy is the energy stored in elastic materials as the result of their stretching or compressing.

Front

How do you calculate kinetic energy?

Back

Kinetic energy (KE) is calculated using the formula: KE = 1/2 mv², where m is mass and v is velocity.

Front

What is the relationship between force and motion?

Back

Force is a push or pull that can cause an object to move, stop, or change direction.

Front

What happens when two forces act in opposite directions?

Back

When two forces act in opposite directions, they should be subtracted from each other to find the net force.

Front

What is work in physics?

Back

Work is done when a force causes an object to move. It is calculated as Work = Force x Distance.

Front

What is friction?

Back

Friction is a force that opposes the motion of an object, acting between surfaces in contact.
