Calculating Net Force

Front

What is net force?

Back

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

Front

What is a balanced force?

Back

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

Front

What is an unbalanced force?

Back

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

Front

What is the unit of force?

Back

N (Newtons)

Front

What does gravity do?

Back

It pulls objects towards the Earth.

Front

If two forces of 5 N and 3 N act in the same direction, what is the net force?

Back

8 N

Front

If a 10 N force pulls to the right and a 4 N force pulls to the left, what is the net force?

Back

6 N to the right.

Front

What is the formula for calculating net force?

Back

Net Force = Force1 + Force2 + ... + ForceN.

Front

What happens to an object at rest when balanced forces act on it?

Back

It remains at rest.

Front

What happens to an object in motion when unbalanced forces act on it?

Back

It accelerates in the direction of the net force.
