Balanced and Unbalanced Forces Assessment

Front

What is net force?

Back

Net force is the total force acting on an object after all the forces are combined. It determines the object's motion.

Front

What happens when forces are balanced?

Back

When forces are balanced, they are equal in size and opposite in direction, resulting in no change in motion.

Front

What happens when forces are unbalanced?

Back

When forces are unbalanced, one force is greater than the other, causing the object to accelerate in the direction of the greater force.

Front

If an object has a net force of 11 N to the left, what does that mean?

Back

It means that the total force acting on the object is 11 Newtons towards the left.

Front

If an object has a net force of 2.5 N to the right, what does that indicate?

Back

It indicates that the total force acting on the object is 2.5 Newtons towards the right.

Front

What is an example of balanced forces?

Back

An example of balanced forces is a book resting on a table; the force of gravity pulling it down is balanced by the table pushing it up.

Front

What is an example of unbalanced forces?

Back

An example of unbalanced forces is pushing a swing; if you push harder than the resistance, the swing moves.

Front

How can you find the net force if two forces are acting in the same direction?

Back

You add the two forces together to find the net force.

Front

How can you find the net force if two forces are acting in opposite directions?

Back

You subtract the smaller force from the larger force to find the net force.

Front

What does a speed graph show?

Back

A speed graph shows how the speed of an object changes over time.
