Front

Friction is a force that acts in an ___________ direction of movement.

Back

Opposite.

Front

Calculate the net force: 10 N to the right and 5 N to the left.

Back

5 N to the right.

Front

What does the equation F = ma represent?

Back

Force equals mass times acceleration.

Front

What are balanced forces?

Back

Forces that have a net force of zero Newtons.

Front

What is unbalanced force?

Back

Forces that result in a net force greater than zero, causing acceleration.

Front

What is the unit of force?

Back

Newton (N).

Front

What is the effect of friction on motion?

Back

Friction opposes motion, slowing down or stopping moving objects.

Front

What is the difference between static and kinetic friction?

Back

Static friction acts on objects at rest, while kinetic friction acts on moving objects.

Front

What is acceleration?

Back
