Newton's Laws Review

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 with the same speed and in the same direction unless acted upon by a net external force.

Front

What is Newton's Second 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 Third Law of Motion?

Back

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

Front

Define momentum.

Back

Momentum is the product of an object's mass and its velocity (p = mv).

Front

What is inertia?

Back

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

Front

What is the formula for calculating momentum?

Back

p = mv, where p is momentum, m is mass, and v is velocity.

Front

What is the acceleration due to gravity on Earth?

Back

9.8 m/s².

Front

How does mass affect acceleration according to Newton's Second Law?

Back

As mass increases, acceleration decreases for a given force.

Front

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

Back

Force equals mass times acceleration (F = ma).

Front

What is an example of Newton's First Law in everyday life?

Back

A book resting on a table will remain at rest until someone pushes it.
