1. Forces & Motion

2. Motion
A change in the position of an object.
Give an example!

3. Force
A force is a
Push Or
Pull

4. Mass
The amount of matter in an object or substance.

5. Describe Acceleration

6. Describe Acceleration
A change in velocity – which may be:
A change in speed
Starting
Stopping
Speeding up
Slowing down
A change in direction
Acceleration is caused by unbalanced forces
More

7. Describe Acceleration
Deceleration is also called negative acceleration - it means an object is slowing down
When acceleration is calculated, it may be a negative number

8. How do we calculate it?
to figure out formulas for F M A

9. Formulas to live by!
F=m x a
m=F/a
A=F/m

10. F M A

11. So, what's the answer?
Mackenzie was pushing a cart that weighed 15 pounds with 20 Newtons of force.
What is the unknown?
What does it equal?

12. Describe Speed

13. Describe Speed Speed is a way to describe motion Types of speed----
Average speed - Rate of motion calculated by dividing the distance traveled by the amount of time it takes to travel that distance
Constant speed - Speed that does not change
Instantaneous speed - Speed of an object at any given time

14. What is the formula used to calculate speed?

15. What is the formula for calculating speed?
Speed is calculated by dividing distance by time –

16. Calculate This Speed
A football field is about 100 m long. If it takes a person 20 seconds to run its length, how fast was the football player running?

17. Remember to include the UNITS!!
Calculate this Speed:
A football field is about 100 m long. If it takes a person 20 seconds to run its length, how fast was the football player running?
Speed = Distance ÷ Time
Speed = 100 m ÷ 20 s
Speed = 5m/s
Remember to include the UNITS!!

18. Velocity The speed AND direction of a moving object.
Ex: Jerrod was going
35mph southeast.

19. Qualitative Data Deals with descriptions.
Data can be observed but not measured.
Colors, textures, smells, tastes, appearance, beauty, etc.
Qualitative → Quality

20. Quantitative Data Deals with numbers. Data which can be measured.
Length, height, area, volume, weight, speed, time, temperature, humidity, sound levels, cost, members, ages, etc.
Quantitative → Quantity
