5.3 Force and Motion

Front

What is friction?

Back

Friction is a force that opposes motion.

Front

What happens when two forces of equal magnitude act in opposite directions?

Back

They will not move at all.

Front

In a scenario where a toy car is on a track made of different materials, where will the most friction occur?

Back

The section with the roughest material, which is section 4.

Front

What type of energy is represented by a moving object?

Back

Kinetic energy.

Front

What is the net force acting on an object?

Back

The combination (total) of all forces acting on an object.

Front

What is the relationship between force and motion?

Back

Force is required to change the motion of an object.

Front

What is kinetic energy?

Back

Kinetic energy is the energy of an object in motion.

Front

What is potential energy?

Back

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

Front

How does friction affect motion?

Back

Friction slows down or stops the motion of an object.

Front

What is the formula for calculating net force?

Back

Net force = total forces acting in one direction - total forces acting in the opposite direction.
