Review Concepts for MP2 Exam

Front

What is potential energy?

Back

Potential energy is the energy stored in an object due to its position or configuration. It is the energy an object has because of its height above the ground.

Front

Which point has the most potential energy in a gravitational field?

Back

The point that is highest above the ground has the most potential energy.

Front

What happens to an object falling at terminal velocity?

Back

At terminal velocity, the object experiences a net force of 0, is in equilibrium, and has no acceleration.

Front

What is the principle of conservation of momentum?

Back

The principle states that the total momentum of a closed system remains constant if no external forces act on it.

Front

What is tension in a rope?

Back

Tension is the force transmitted through a rope or string when it is pulled tight by forces acting from opposite ends.

Front

What is Newton's Third Law of Motion?

Back

For every action, there is an equal and opposite reaction.

Front

What is energy?

Back

Energy is the ability to do work.

Front

What is kinetic energy?

Back

Kinetic energy is the energy of an object due to its motion, calculated as KE = 1/2 mv², where m is mass and v is velocity.

Front

What is the formula for gravitational potential energy?

Back

Gravitational potential energy is calculated as PE = mgh, where m is mass, g is the acceleration due to gravity, and h is height.

Front

What is the difference between mass and weight?

Back

Mass is the amount of matter in an object, while weight is the force exerted by gravity on that mass.
