Differentiate between speed and velocity.
3m/s
3m/s north
distance divided by time
distance divided by time with direction
speed with direction
A block is pulled 0.90 m to the right in 2.5 s.
What is the block's average speed to the nearest hundredth of a m/s?
What is the speed of the toy during trial 1? (do NOT round)
What is the speed of the toy during trial 2? (do NOT round)
Calculating Speed from a Motion Graph
The motion graph below represents a bug’s journey from his home out to search for food. When he collects food, he returns back to his home to store his findings. He then leaves his home again in search of more food and stops when he finds another supply.
What is the bug's distance in meters when he leaves home for the first time (O to A)?
Type the number only, do not include units.
How much time in minutes elapses between O and A?
Type the number only, do not include units.
What is the bug’s speed in meters/minute when he leaves his home the first time (from O to A)?
Type the number only, do not include units.
What is the distance traveled in meters while he is collecting food the first time (from A to B)?
Type the number only, do not include units.
How much time in minutes elapses while he is collecting food the first time (from A to B)?
Type the number only, do not include units.
What is the bug’s speed in meters/minute while he is collecting food the first time (from A to B)?
Type the number only, do not include units.
What is the bug’s distance traveled in meters when he is returning home with his first food findings (from B to C)?
Type the number only, do not include units.
What is the time elapsed in minutes when he is returning home with his first food findings (from B to C)?
Type the number only, do not include units.
What is the average speed in meters/minute when he is returning home with his first food findings (from B to C)?
Type the number only rounded to the nearest hundredth, do not include units.
What is the bug doing from B-C?
Calculate the speed at 10 minutes. Numbers only.
Calculate the speed at 20 minutes. Numbers only.
