# Speed, Velocity  and Acceleration

Summary of Acceleration, Speed and Velocity Including Distance-time and Velocity-time graphs

• Speed, Velocity  and Acceleration
• Velocity
• Velocity = Distance / Time
• You must give a direction
• Simply is the speed of something in a given direction
• Velocity is given in m/s but ...
• You must give a direction
• On velocity -time graph, objects travelling at a constant are represented by a straight line
• Acceleration is represented by a line slopping upwards
• Deceleration is found by a line slopping downwards
• Increasing acceleration is represented by a curved line
• Speed
• Speed= Distance / Time
• On a distance-time graph a stationary object is represented by a straight flat line
• Objects traveling at a constant speed are represented by a slopping line
• Acceleration
• Acceleration = Change in Velocity / Time Taken
• Acceleration is when an object is going faster
• Deceleration is when an object is slowing down
• Acceleration is when an object is going faster
• The units for Acceleration is m/s^2
