Distance Time and Speed

What is distance?

• an object's overall change in position (start to end)

• how much ground an object has covered during its motion

• how fast an object is moving

• how long it takes an object to move from start to end

What is speed?

• an object's overall change in position (start to end)

• how much ground an object has covered during its motion

• how fast an object is moving

• how long it takes an object to move from start to end
