Balanced and Unbalanced Forces Assessment

Front

What is a force?

Back

A force is a push or pull that can change the motion of an object.

Front

What is net force?

Back

Net force is the total force acting on an object after all the forces are combined.

Front

What happens when forces are balanced?

Back

When forces are balanced, the object does not move or continues to move at a constant speed.

Front

What happens when forces are unbalanced?

Back

When forces are unbalanced, the object will accelerate in the direction of the greater force.

Front

What is friction?

Back

Friction is a force that opposes motion between two surfaces that are in contact.

Front

What is an example of unbalanced forces?

Back

A toy car being pushed harder on one side than the other, causing it to move.

Front

What is an example of balanced forces?

Back

Two people pulling on a rope with equal force in opposite directions.

Front

How do you calculate net force?

Back

To calculate net force, add all the forces acting in one direction and subtract the forces acting in the opposite direction.

Front

What is the unit of force?

Back

The unit of force is Newton (N).

Front

What does it mean if an object is at rest?

Back

If an object is at rest, it means that the net force acting on it is zero.
