Fall 2024 Physics Final Review B

Front

What is the formula for calculating kinetic energy?

Back

Kinetic Energy (KE) = 1/2 * m * v², where m is mass and v is velocity.

Front

What is the unit of kinetic energy?

Back

The unit of kinetic energy is the Joule (J).

Front

How does air resistance affect the motion of falling objects?

Back

Air resistance decreases the object's speed.

Front

What is Newton's second law of motion?

Back

Newton's second law states that Force (F) = mass (m) * acceleration (a).

Front

What is the unit of force?

Back

The unit of force is the Newton (N).

Front

How do you calculate the force required to accelerate an object?

Back

Force = mass * acceleration.

Front

What is the principle of conservation of momentum?

Back

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

Front

What happens to momentum in an inelastic collision?

Back

In an inelastic collision, momentum is conserved, but kinetic energy is not.

Front

What is the formula for calculating momentum?

Back

Momentum (p) = mass (m) * velocity (v).

Front

What is Newton's third law of motion?

Back

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