SPEEDSPEED

DEFINITION Speed measures how quickly an object moves a distance.Speed is equal to the distance the object travels divided by the time it took the object to travel that distance.Speed is always written as units of distance (like meters) over units of time (like seconds)

Page 4: Today’s Objective We will be able to calculate the speed and velocity of an object in motion by analyzing given data

SPEEDSPEED

EQUATION

Speed = distance ÷ time

ORS = D

T

SPEEDSPEED

EXAMPLEA car travels 50 miles in 2 hours. What is its average speed?

Speed = distance ÷ time

•Speed = ?_ Distance = 50 miles Time= 2 hours

•Set up the Equation: Speed = 50 miles (divide)

2 hours

•Divide and solve: Speed = 25 miles in 1 hour

•The average speed is 25 miles per hour

VELOCITYVELOCITY

DEFINITION

Velocity is how fast something moves in a certain DIRECTION. It is calculated the same way as speed, but you need to add the direction that the object is traveling to your answer.
