Physics Fall Review 2024

Front

Energy due to motion is ____________ energy.

Back

Kinetic energy is the energy an object possesses due to its motion.

Front

What segment of the graph shows no motion, or standing still?

Back

A segment of the graph that shows no motion is represented by a horizontal line.

Front

Complete the statement: When an object is pushed, it __________________ with an equal and opposite force.

Back

When an object is pushed, it always pushes back with an equal and opposite force (Newton's Third Law of Motion).

Front

A baseball bat applies a force of 500 N to a ball for 0.1s. What was the impulse on the ball?

Back

Impulse is calculated as Force x Time. Therefore, the impulse is 500 N x 0.1 s = 50 N.s.

Front

During which interval is the object traveling at a constant velocity?

Back

An object travels at a constant velocity when the graph shows a straight line with a constant slope.

Front

What is the formula for kinetic energy?

Back

The formula for kinetic energy (KE) is KE = 1/2 mv², where m is mass and v is velocity.

Front

Define potential energy.

Back

Potential energy is the stored energy in an object due to its position or state.

Front

What is Newton's First Law of Motion?

Back

An object at rest stays at rest, and an object in motion stays in motion unless acted upon by a net external force.

Front

What is the relationship between force, mass, and acceleration?

Back

According to Newton's Second Law, Force = Mass x Acceleration (F = ma).

Front

What is the principle of conservation of energy?

Back

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