PSA: Balanced versus Unbalanced Forces

Front

What is the net force when all forces acting on an object are equal and opposite?

Back

0 N (Balanced Forces)

Front

How will an object move if the net force acting on it is greater than zero?

Back

It will accelerate in the direction of the net force.

Front

What is the net force if an object has 40 N of force acting to the right and 0 N acting to the left?

Back

40 N right

Front

What is inertia?

Back

The tendency of an object at rest to stay at rest unless acted upon by a force.

Front

What are balanced forces?

Back

Forces that are equal in size and opposite in direction, resulting in a net force of 0 N.

Front

What are unbalanced forces?

Back

Forces that are not equal and opposite, resulting in a net force greater than 0 N.

Front

If a car is moving at a constant speed in a straight line, what can be said about the forces acting on it?

Back

The forces are balanced.

Front

What happens to an object at rest when an unbalanced force acts on it?

Back

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

Front

What is the effect of gravity on an object in free fall?

Back

It accelerates downward due to the force of gravity.

Front

If two forces of 30 N and 50 N act in the same direction, what is the net force?

Back

80 N in the direction of the forces.
