Motion Graphs

Remember:

• Motion is a change in position measured by distance and time.

• Speed tells us the rate at which an object moves.

• Velocity tells the speed and direction of a moving object.

• Acceleration tells us the rate speed or direction changes.

Motion Graphs

DISTANCE-TIME GRAPHS

Summary:

A distance-time graph tells us how far an object has moved with time.

• The steeper the graph, the faster the motion.

• A horizontal line means the object is not changing its position - it is not moving, it is at rest.

• A downward sloping line means the object is returning to the start.

Motion Graphs

SPEED-TIME GRAPHS

Summary:

A speed - time graph shows us how the speed of a moving object changes with time.

• The steeper the graph, the greater the acceleration.

• A horizontal line means the object is moving at a constant

speed.

• A downward sloping line means the object is slowing down.
