Forces and Motion Notes 3

Front

Newton's First Law of Motion

Back

Inertia - Everything just keeps moving or resting if there is no unbalanced force.

Front

Elephant vs. human

Back

It is harder to change an elephant's motion than a human's motion due to greater mass.

Front

Newton's Second Law formula

Back

Force = Mass x Acceleration

Front

Newton's Second Law

Back

The acceleration of an object depends on its mass and the force applied.

Front

Unit of force in the formula F = m x a

Back

Newton (N)

Front

How do you calculate acceleration using force and mass?

Back

Acceleration is calculated by dividing force by mass. A = F/M

Front

Newton's Third Law of Motion.

Back

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

Front

Reason it's easier to push a bicycle than a car

Back

Less mass, less force needed for same acceleration

Front

Newton’s third law and rocket takeoff

Back

Action-reaction: Gases forced out of rocket engine push down, causing rocket to go up.
