Calculating Force

Front

What is Newton's second law of motion?

Back

F = MA (Force equals mass times acceleration)

Front

What does force mean?

Back

A push or pull on an object.

Front

In a tug of war, if one team pulls with a force of 45 N to the left and the other with 50 N to the right, what is the net force?

Back

5 N to the right.

Front

What is the net force if two equal forces of 20 N are acting in opposite directions?

Back

0 N (Balanced forces)

Front

What is a balanced force?

Back

When two forces acting on an object are equal in size and opposite in direction.

Front

What is an unbalanced force?

Back

When two forces acting on an object are not equal, causing the object to move.

Front

If a car has a mass of 2,000 kg and accelerates at 3 m/s², what is the force applied?

Back

6,000 N (F = MA)

Front

What happens to an object at rest when a net force is applied?

Back

It will start to move in the direction of the net force.

Front

What is the unit of force?

Back

Newton (N)

Front

If a force of 10 N is applied to the right and a force of 5 N is applied to the left, what is the net force?

Back

5 N to the right.
