Force and Motion Review 1

Front

What is force?

Back

A force is a push or pull that can cause an object to accelerate, change direction, or change shape.

Front

What is motion?

Back

Motion is the change in position of an object over time.

Front

What are unbalanced forces?

Back

Unbalanced forces are forces that cause a change in the motion of an object because they do not cancel each other out.

Front

What is net force?

Back

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

Front

What is the relationship between force and motion?

Back

Force causes motion; an object will not move unless a force is applied.

Front

What is the effect of applying a force in the opposite direction of motion?

Back

Applying a force in the opposite direction of motion will slow down the object.

Front

What is Newton's Third Law of Motion?

Back

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

Front

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

Back

Subtract the smaller force from the larger force and the direction of the larger force will be the direction of the net force.

Front

What happens to an object at rest when unbalanced forces act on it?

Back

An object at rest will start to move in the direction of the net force.
