Sir Isaac Newton English scientist Devised the Laws of Motion

The 1st Law of Motion Objects at rest tend to stay at rest unless acted on by some outside force Object is at rest Object in motion

The 2nd Law of Motion Force = Mass x Acceleration The force needed to move an object depends on its mass and how fast you want to move it.

The 3rd Law of Motion For every action there is an = an opposite reaction

An action force is opposed by a … reaction force

The action force of a rocket is produced by hot gases coming out of the bottom of the rocket. Reaction force Gravitational force

The tendency of an object to stay either in motion or at rest is called… inertia

What can change the speed and direction of a moving object? An outside force

On earth, an object in motion will eventually stop because of friction and… gravity

The amount of matter in an object is its… Mass The watermelon has more mass Requires more force to lift

What is speed? Speed measures how quickly an object moves over a certain distance.

What is velocity? Velocity measures the speed and the direction that an object travels.

What is acceleration? Acceleration measures the rate of change in velocity.
