Forces

Front

What is net force?

Back

The overall force acting on an object when all the individual forces are combined.

Front

If two forces of equal magnitude act in opposite directions, what is the net force?

Back

0 N, because the forces cancel each other out.

Front

What are balanced forces?

Back

Forces that are equal in size and opposite in direction, resulting in no change in motion.

Front

What are unbalanced forces?

Back

Forces that are not equal and opposite, causing a change in motion of an object.

Front

What happens to a stationary object when balanced forces act on it?

Back

It remains stationary.

Front

What happens to a moving object when unbalanced forces act on it?

Back

It accelerates in the direction of the net force.

Front

In a tug of war, if one team pulls with a greater force than the other, what happens?

Back

The team with the greater force wins, and the net force is in their direction.

Front

What is the effect of friction on motion?

Back

Friction opposes motion, acting as a force that resists the movement of objects.

Front

How can you calculate net force when multiple forces are acting on an object?

Back

Add the forces acting in one direction and subtract the forces acting in the opposite direction.

Front

What is the unit of force?

Back

Newton (N).
