Balanced and Unbalanced Forces

Front

Balanced forces

Back

Equal forces acting in opposite directions

Front

Unbalanced forces

Back

Unbalanced forces occur when two forces acting on an object are not equal in size and opposite in direction, causing a change in the object's motion.

Front

How do you calculate the net force when two forces are acting in the same direction?

Back

Add the magnitudes of the two forces together

Front

How do you calculate the net force when two forces are acting in opposite directions?

Back

Subtract the smaller force from the larger force

Front

What is the effect of unbalanced forces on an object at rest?

Back

The object will start moving.

Front

What is the effect of unbalanced forces on an object in motion?

Back

Unbalanced forces cause a change in the object's motion.

Front

Example of a situation where balanced forces are acting on an object.

Back

When a person is standing still on the ground.

Front

Example of a situation where unbalanced forces are acting on an object.

Back

When a person pushes a shopping cart.

Front

How do balanced forces affect the motion of an object?

Back

Balanced forces keep the object at rest or moving at a constant speed.

Front

Explain how unbalanced forces affect the motion of an object.

Back

Unbalanced forces cause the object to accelerate in the direction of the greater force.
