Force, Motion, Energy Test

Front

What is kinetic energy?

Back

Kinetic energy is the energy an object has due to its motion. The faster an object moves, the more kinetic energy it has.

Front

At what point does a boulder rolling down a hill have the most kinetic energy?

Back

Just before the bottom of the hill.

Front

What is the force required to move an object?

Back

The force required to move an object depends on its mass and the friction acting on it. More mass usually means more force is needed.

Front

If one box requires 60 N of force to move, how much force is needed for a box with twice the mass?

Back

120 N.

Front

What force causes a book to fall off a shelf?

Back

Gravity.

Front

What is acceleration?

Back

Acceleration is the rate at which an object changes its velocity. It can involve speeding up, slowing down, or changing direction.

Front

Which of these is NOT an example of acceleration?

Back

Driving at a constant speed in one direction.

Front

What force causes raindrops to slide down a window?

Back

Gravity.

Front

What is friction?

Back

Friction is a force that opposes the motion of an object. It occurs when two surfaces rub against each other.

Front

What is the relationship between mass and force?

Back

The greater the mass of an object, the more force is needed to move it.
