Newtons Laws of Motion

Front

What does Newton's third law state?

Back

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

Front

What is the attractive force that exists between all objects that have mass?

Back

Gravity.

Front

What does Newton's second law describe?

Back

The relationship between force, mass, and acceleration; specifically, F=ma.

Front

What happens to forces when a marble speeds up rolling down a ramp?

Back

The forces are unbalanced.

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

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

Front

What is the formula for calculating weight?

Back

Weight = mass × gravity (W = mg).

Front

What is the law of universal gravitation?

Back

Every point mass attracts every other point mass with a force that is directly proportional to the product of their masses and inversely proportional to the square of the distance between their centers.

Front

What is the difference between mass and weight?

Back

Mass is the amount of matter in an object, while weight is the force exerted by gravity on that mass.

Front

What is an example of Newton's first law in everyday life?

Back

A passenger lurches forward in a car when it suddenly stops.
