1. Motion and Force

2. Newton Sir Isaac Newton discovered the 3 laws of motion.
Newton published Philosophae Naturalis Principia Mathematica

3. 1st Law of Motion
1st Law Inertia – If an object is at rest it will remain at rest unless acted on by an outside force
Same is true if an object is in motion!

4. 2nd Law of Motion
2nd Law –
F = M x A
M = F / A
A = F / M

5. 3rd Law of Motion
3rd Law – For every action there is an equal and opposite reaction

6. Force
A push or pull that causes an object to move, stop, or change direction
Force is measured in Newton’s (N)

7. Forces can affect motion in several ways:
→ They can make objects start moving.
→ They can make objects move faster.
→ They can make objects move slower.
→ They can make objects stop moving.
→ They can make objects change direction.

8. Distance Distance is the measurement from one point to another.
Distance may refer to a physical length, a period of time, or an estimation.

9. Friction
Friction is a force that acts against or stops motion when two surfaces rub against each other.

10. Speed
Speed is a measure of the distance an object moves in a given amount of time.
During a typical trip to school, your car will undergo a series of changes in its speed.

11. Velocity
Velocity is speed but with a specific direction

12. Acceleration & Deceleration
Acceleration is an increase in speed.
Deceleration is a decrease in speed.

13. Slope
Slope is used to describe the steepness, incline, or grade of a straight line.

14. Gravity
Gravity is the force that pulls all objects in the universe toward one another.
