Acceleration
9
Force and Motion 2
To calculate an objects acceleration, you need
to know what?
Starting velocity, final velocity, and the time
it takes to change velocity
10

Newtons
11
Force and Motion 4

• The SI unit for speed is

m/s or meters/second
12
Force and Motion 5

• Do you accelerate if you travel in a circle at 50
  m/s?

Yes because you are constantly changing direction

17
Friction3
The amount of friction depends on 2 factors, what
are they?

• Amount of force pushing the surfaces together
• Texture (roughness or smoothness) of the surfaces

18
Friction4

• Does surface area affect the amount of friction?

No
19
Gravity1

• Gravitational force depends on the _________ of
  the objects and the distance between them.

Mass
20
Gravity2

• If Earths mass doubled, what would happen to
  your weight and why?

• Your weight would increase because gravity
  increases.

21
Gravity3

• The force of gravity is ____________ between two
  objects that have greater masses.

greater
22
Gravity4

• Objects of any size exert a ____________ force.

gravitational
23
Gravity5

25
Vocabulary 2

• What describes the relationship between force,
  mass, and distance?

• Law of Universal Gravitation

26
Vocabulary 3

• The distance traveled divided by the time it took
  to travel that distance determines an objects
