FLASHCARD-Balanced, Unbalanced,& Net Force Examples Unit 4

Front

What are balanced forces?

Back

Balanced forces are forces that are equal in size and opposite in direction, resulting in no change in motion.

Front

What are unbalanced forces?

Back

Unbalanced forces are forces that are not equal in size or opposite in direction, causing a change in motion.

Front

What is net force?

Back

Net force is the overall force acting on an object when all the individual forces are combined.

Front

If the net force is zero, what can we say about the forces acting on the object?

Back

The forces acting on the object are balanced.

Front

If an object is moving to the right and the net force is unbalanced, which direction will it move?

Back

It will continue to move to the right if the unbalanced force is also to the right.

Front

What does Newton's 3rd Law state?

Back

For every action, there is an equal and opposite reaction.

Front

What happens to a stationary object when unbalanced forces act on it?

Back

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

Front

What is an example of equal and opposite forces?

Back

A book resting on a table experiences the force of gravity downward and the normal force from the table upward.

Front

How can you determine the direction of motion when forces are unbalanced?

Back

The object will move in the direction of the greater force.

Front

What is the effect of balanced forces on a moving object?

Back

Balanced forces will not change the motion of a moving object; it will continue moving at a constant speed in a straight line.
