Newton's Laws of Motion Flashcard

Front

What is a balanced force?

Back

A balanced force occurs when two forces acting on an object cancel each other out, resulting in no change in motion.

Front

What happens to acceleration when mass increases?

Back

Increasing the mass of an object decreases its acceleration when the same force is applied.

Front

What is an unbalanced force?

Back

An unbalanced force occurs when one force acting on an object is greater than another force, causing a change in motion.

Front

How do you get a heavier object to move at the same rate as a lighter object?

Back

You need to push the heavier object with more force than the lighter object.

Front

What science concept is demonstrated when a balloon flies around after being released?

Back

The concept of action-reaction forces, as described by Newton's Third Law of Motion.

Front

What is Newton's First Law of Motion?

Back

An object at rest stays at rest, and an object in motion stays in motion unless acted upon by a net external force.

Front

What is inertia?

Back

Inertia is the tendency of an object to resist changes in its state of motion.

Front

What is the relationship between force, mass, and acceleration?

Back

According to Newton's Second Law, force equals mass times acceleration (F = ma).

Front

What is an example of an action-reaction force?

Back

When you jump off a small boat, you push the boat backward while you move forward.

Front

What is the effect of friction on motion?

Back

Friction is a force that opposes motion, making it harder for objects to move.
