Motion

• Motion is a change in position of an object over time.
• Vector - magnitude and direction
• Scalar - magnitude only
• Distance is how far an object has traveled. (start to end)
• Displacement is how far from the starting point an object actually moved. (start and end)
• Displacement does not equal distance traveled.
• GIVEN - # & unit + symbol 

  ASKED - symbol = ?

  FORMULA  - 

  SOLUTION - Substitution 

  ANSWER- 
• Distance, (scalar) refers to how fast a body is moving and is defined as the distance conveyed per unit of time travel. 
• Velocity is a measure of how fast something moves in a particular direction.
• Velocity is just speed with direction.
• Acceleration is a change in velocity over time.
• Velocity is speed and direction.
• Speeding up - acceleration (positive)
• Slowing down - deceleration (negative)
• Formula for acceleration:

  final velocity - initial velocity / time

  vf - vi / t
