Energy and Force Pre-Assessment

Front

What is the net force?

Back

The net force is the overall force acting on an object when all the individual forces are combined. It determines the object's motion.

Front

What type of force causes a thrown rock to come down?

Back

Gravity is the force that pulls objects toward the Earth, causing a thrown rock to fall.

Front

If both forces are going in the same direction, what should you do with those forces?

Back

You should add those forces together.

Front

What type of energy do your ears hear?

Back

Sound energy is the type of energy that is detected by our ears.

Front

What force holds the planets in motion around the sun?

Back

Gravitational force holds the planets in orbit around the sun.

Front

What is energy?

Back

Energy is the ability to do work or cause change.

Front

What is force?

Back

A force is a push or pull on an object that can cause it to move, stop, or change direction.

Front

What is the unit of force?

Back

The unit of force is the Newton (N).

Front

What happens when forces are balanced?

Back

When forces are balanced, the net force is zero, and the object remains at rest or continues to move at a constant speed.

Front

What is kinetic energy?

Back

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