Motion

1

• Motion

• Change in position during a time period
• 3 types of motion
• Speed
• Velocity
• Acceleration

2

• Speed

• 1. Definition Rate at which an object moves
• 2. Formula Distance divided by time (d/t)
• 3. Units m/s or km/s

3

• Speed

• 4. Constant speed - speed that doesnt change
• 5. Average speed- add speeds, divide by total
  number

4

• Velocity

• 1. Definition Describes speed plus direction
  (n, s, e, w)
• 2. Formula D/T plus direction
• 3. Units m/s or km/s, north, south, east or
  west

5

• Velocity

• 4. Velocities can be combined
• Add velocities when in same direction
• Velocities in opposite direction subtract

6

• Acceleration

• 1. Definition Rate of change in velocity
• Speeding up, slowing down, changing direction
• 2. Formula Final velocity minus original
  velocity, divided by time
• 3. Units m/s/s or km/s/s

7

• Acceleration

• 4. Increasing velocity - positive acceleration
• 5. Decreasing velocity - negative acceleration-
  deceleration

8

• Momentum

• 1. Definition Depends on objects mass and
  velocity
• Related to force upon impact
• 2. Formula Mass x velocity
• 3. Units Kg.m/s
