Unit 05: Force, Motion & Energy Practice

Front

What is friction?

Back

Friction is a force that opposes the motion of an object when it comes into contact with another surface.

Front

What is kinetic energy?

Back

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

Front

What is potential energy?

Back

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

Front

What happens to an object's motion during a collision?

Back

The motion of the objects involved can change, such as speed or direction.

Front

What is the role of gravity?

Back

Gravity is a force that pulls objects toward each other, such as the Earth pulling objects toward its center.

Front

What is the difference between speed and velocity?

Back

Speed is how fast an object is moving, while velocity includes both speed and direction.

Front

What is the formula for calculating kinetic energy?

Back

Kinetic energy (KE) = 1/2 * mass (m) * velocity (v)².

Front

What is the effect of friction on a moving object?

Back

Friction slows down the object and can eventually stop it.

Front

What is motion?

Back

Motion is the change in position of an object over time.

Front

What is inertia?

Back

Inertia is the tendency of an object to resist changes in its state of motion.
