Newton's Laws and Momentum

Front

What is a force?

Back

A push or pull on an object.

Front

What does Newton's 3rd Law state?

Back

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

Front

What are balanced forces?

Back

When two equal forces act in opposite directions on an object.

Front

How do you calculate acceleration?

Back

Acceleration = Force / Mass.

Front

What is the acceleration of a 50 kg object pushed with a force of 500 newtons?

Back

10 m/s².

Front

What is the difference between speed and velocity?

Back

One has direction, and the other does not.

Front

What is momentum?

Back

The product of an object's mass and its velocity.

Front

What is inertia?

Back

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

Front

What is Newton's 1st Law?

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 Newton's 2nd Law?

Back

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