TodayToday’’s Objectives ObjectiveWe will be able to calculate the
speed and velocity of an object in motion by analyzing given data.
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)
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
GP 1GP 1A car travels 300 miles to the
beach and gets there in 6 hours. On average, how fast was the car traveling on the trip?
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.
GP 3GP 3A plane takes off from Boston
and travels 3000 miles across the country to San Francisco, California in 6 hours. What is the velocity of the plane?
GP 4GP 4Two boys are running in opposite
directions at 4 m/s. Explain your answers
Do they have the same speed?Do they have the same velocity?
