Honors Physics Final Exam Review

Front

What is kinetic energy?

Back

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

Front

At which point in a pendulum's swing is kinetic energy highest?

Back

Kinetic energy is highest at the lowest point of the swing (point 3), where the speed is greatest.

Front

How do you calculate momentum?

Back

Momentum (p) is calculated using the formula p = mv, where m is mass and v is velocity.

Front

What is the momentum of a 50 kg ball rolling at 5 m/s?

Back

The momentum is 250 kg*m/s.

Front

What is net force?

Back

Net force is the total force acting on an object after all the forces are combined.

Front

If a crate is pushed with a force of 100 N and moves at constant velocity, what is the net force?

Back

The net force is 0 N, as the forces are balanced.

Front

What do waves transfer?

Back

Waves transfer energy.

Front

Does more mass mean an object falls faster?

Back

False. The acceleration due to gravity is constant for all objects, regardless of mass.

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 potential energy?

Back

Potential energy is the stored energy in an object due to its position or state, calculated as PE = mgh, where m is mass, g is acceleration due to gravity, and h is height.
