Page 2: 1. Speed, Velocity, & Acceleration 2 You know a car is in motion if you see it in one place 3 then in another place in relation to an object.

Speed, Velocity, & Acceleration

2

Page 3: 1. Speed, Velocity, & Acceleration 2 You know a car is in motion if you see it in one place 3 then in another place in relation to an object.

You know a car is in motion if you see it in one place

3

then in another place in relation to an object

Page 4: 1. Speed, Velocity, & Acceleration 2 You know a car is in motion if you see it in one place 3 then in another place in relation to an object.

3 ways to change motion

4

1. Speed2. Velocity3. Acceleration

Page 5: 1. Speed, Velocity, & Acceleration 2 You know a car is in motion if you see it in one place 3 then in another place in relation to an object.

5

Vocabulary:

speed

The distance something moves in a certain time

Speed = Distance Time

Page 6: 1. Speed, Velocity, & Acceleration 2 You know a car is in motion if you see it in one place 3 then in another place in relation to an object.

Many people can walk 2 miles in 1 hour

6

Speed =2 miles1 hour

Their speed is 2 miles per hour

It is often written 2 miles / hour

Page 7: 1. Speed, Velocity, & Acceleration 2 You know a car is in motion if you see it in one place 3 then in another place in relation to an object.

7

Some people can run 7 miles an hour

or7 miles / hour

The speed of 7 miles / hour is faster than 2 miles / hour

Page 8: 1. Speed, Velocity, & Acceleration 2 You know a car is in motion if you see it in one place 3 then in another place in relation to an object.

8

Vocabulary:

velocity

Speed in a certain direction

Page 9: 1. Speed, Velocity, & Acceleration 2 You know a car is in motion if you see it in one place 3 then in another place in relation to an object.

If you are running at 7 miles / hour along a straight path

9

your velocity is the same as your speed

Page 10: 1. Speed, Velocity, & Acceleration 2 You know a car is in motion if you see it in one place 3 then in another place in relation to an object.

But if you are running around a track you are changing

direction

10

Your speed is the same, but your velocity is changing

Page 11: 1. Speed, Velocity, & Acceleration 2 You know a car is in motion if you see it in one place 3 then in another place in relation to an object.

Velocity changes when the direction of the motion

changes

11

Page 12: 1. Speed, Velocity, & Acceleration 2 You know a car is in motion if you see it in one place 3 then in another place in relation to an object.

12

Vocabulary:

acceleration

a change in velocity

Page 13: 1. Speed, Velocity, & Acceleration 2 You know a car is in motion if you see it in one place 3 then in another place in relation to an object.

If you pedal a bicycle so that it speeds up

13

that is positive acceleration

Page 14: 1. Speed, Velocity, & Acceleration 2 You know a car is in motion if you see it in one place 3 then in another place in relation to an object.

If you use the brakes to slow down

14

that is negative acceleration
