7th grade-Newton's laws

Front

What is Newton's 1st Law of Motion?

Back

An object at rest stays at rest, and an object in motion stays in motion at a constant velocity unless acted upon by an unbalanced force.

Front

What is Newton's 2nd Law of Motion?

Back

The acceleration of an object is directly proportional to the net force acting on it and inversely proportional to its mass. (F = ma)

Front

What is Newton's 3rd Law of Motion?

Back

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

Front

What is inertia?

Back

The tendency of an object to resist changes in its state of motion.

Front

What is acceleration?

Back

The rate at which an object's velocity changes over time.

Front

What is mass?

Back

The amount of matter in an object, typically measured in kilograms.

Front

What is weight?

Back

The force exerted by gravity on an object, calculated as mass times the acceleration due to gravity (W = mg).

Front

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

Back

According to Newton's 2nd Law, force equals mass times acceleration (F = ma).

Front

What happens to an object's motion when an unbalanced force acts on it?

Back

The object's motion changes; it may start moving, stop, or change direction.

Front

How does mass affect acceleration?

Back

A larger mass requires more force to achieve the same acceleration as a smaller mass.
