• Module C
• Chapter 1
• Grade 5

2
Sir Isaac Newton

• English scientist
• Devised the Laws of Motion

3
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

4
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.

5
The 3rd Law of Motion

• For every action there is an an opposite
  reaction

6
An action force is opposed by a

• reaction force

7
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

8
The tendency of an object to stay either in
motion or at rest is called

• inertia

9
What can change the speed and direction of a
moving object?

• An outside force

10
On earth, an object in motion will eventually
stop because of friction and

• gravity

11
The amount of matter in an object is its

• Mass
• The watermelon has more mass
• Requires more force to lift

12
What is speed?

• Speed measures how quickly an object moves over a
  certain distance.

13
What is velocity?

• Velocity measures the speed and the direction
  that an object travels.

14
What is acceleration?

• Acceleration measures the rate of change in
  velocity.
