Kickball in Motion Module C Chapter 1 Grade 5
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. • Action force • 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.
