Newton's Laws Test Review Flashcards

Flashcards for reviewing Newton's Laws of Motion

Newton's 1st Law

An object at rest remains at rest, and an object in motion remains in motion unless acted upon by an unbalanced force.

Newton's 2nd Law

F = ma. The larger the unbalanced force, the greater the acceleration. The greater the mass, the harder to accelerate.

Newton's 3rd Law

For every force, there is an equal and opposite force. Action and reaction are equal and opposite.

Acceleration

Changing velocity, including speeding up, slowing down, and changing direction.

Balanced Forces

Forces applied to an object that cancel each other out, resulting in no acceleration.

Net Force

The overall force acting on an object, causing it to accelerate in that direction.

Positive and Negative Acceleration

Slowing down is expressed as a negative acceleration, while speeding up is a positive acceleration.

Formula for Force

F = m x a

Balanced Forces

Without motion

Unbalanced Forces

There will be a change in motion

Gravity

Constant force pulling down
