Newton's Law and Forces

Front

What is Newton's 2nd law of motion?

Back

Force = Mass multiplied by acceleration.

Front

When something has speed in a certain direction, it is called ___________.

Back

Velocity.

Front

Forces always act in equal and opposite pairs. This is known as ___________.

Back

Newton's 3rd Law.

Front

What is the unit of mass?

Back

kg.

Front

Acceleration of an object happens when things __________.

Back

All of the above (slow down, go faster, change direction).

Front

What is the formula for calculating force?

Back

Force = Mass x Acceleration.

Front

What does Newton's 1st Law state?

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 the difference between speed and velocity?

Back

Speed is a scalar quantity (magnitude only), while velocity is a vector quantity (magnitude and direction).

Front

What is inertia?

Back

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

Front

What is the unit of force?

Back

Newton (N).
