3. CALCULATING SPEED KEY- TO CALCULATE SPEED OF AN OBJECT DIVIDE THE DISTANCE THE OBJECT TRAVELS BY THE AMOUNT OF TIME IT TAKES TO TRAVEL THE DISTANCE- SPEED= DISTANCE/TIME KEY- TO CALCULATE SPEED OF AN OBJECT DIVIDE THE DISTANCE THE OBJECT TRAVELS BY THE AMOUNT OF TIME IT TAKES TO TRAVEL THE DISTANCE- SPEED= DISTANCE/TIME S = D/T S = D/T EX- A CYCLIST TRAVELS 30KM IN 2 HR EX- A CYCLIST TRAVELS 30KM IN 2 HR WHAT IS THE SPEED PER HR? S= distance 30km divided by time 2hrs or 30/2 = ? Km per hour WHAT IS THE SPEED PER HR? S= distance 30km divided by time 2hrs or 30/2 = ? Km per hour

5. CONTD AVERAGE SPEED (V) - IS THE TOTAL DISTANCE DIVIDED BY TOTAL TIME AVERAGE SPEED (V) - IS THE TOTAL DISTANCE DIVIDED BY TOTAL TIME EX- RUNNER TRAVELS 10 KM IN FIRST 2 HRS AND 5KM IN THE LAST HR EX- RUNNER TRAVELS 10 KM IN FIRST 2 HRS AND 5KM IN THE LAST HR TOTAL DISTANCE =15…….TOTAL TIME 3HRS TOTAL DISTANCE =15…….TOTAL TIME 3HRS What is the AVERAGE SPEED (V)= total D/ total T time?…… What is the AVERAGE SPEED (V)= total D/ total T time?……

6. calculate If a car vtravels 300 miles in 6 hr how fast is it going? If a car vtravels 300 miles in 6 hr how fast is it going? If you move 10 meters in 2 seconds what is your speed? If you move 10 meters in 2 seconds what is your speed? A plane travels 6000 miles in 24 hours what is its speed? A plane travels 6000 miles in 24 hours what is its speed?

7. VELOCITY VELOCITY- IS THE SPEED AND DIRECTION OF AN OBJECT. VELOCITY- IS THE SPEED AND DIRECTION OF AN OBJECT. EX- VELOCITY OF A STORM COULD BE 25KM/h TO THE WEST EX- VELOCITY OF A STORM COULD BE 25KM/h TO THE WEST KEY – CHANGES IN VELOCITY MAY INCLUDE CHANGES OF SPEED, CHANGES OF DIRECTION, OR BOTH KEY – CHANGES IN VELOCITY MAY INCLUDE CHANGES OF SPEED, CHANGES OF DIRECTION, OR BOTH

8. GRAPHING SPEED KEY – THE STEEPNESS OF A LINE IS CALLED THE SLOPE KEY – THE STEEPNESS OF A LINE IS CALLED THE SLOPE KEY- THE SLOPE OF A DISTANCE- VERSUS-TIME GRAPH REPRESENTS SPEED, THAT IS, THE RATE THAT DISTANCE CHANGES IN RELATION TO TIME. KEY- THE SLOPE OF A DISTANCE- VERSUS-TIME GRAPH REPRESENTS SPEED, THAT IS, THE RATE THAT DISTANCE CHANGES IN RELATION TO TIME.
