Front

What is speed?

Back

Speed is the distance traveled per unit of time, typically measured in meters per second (m/s) or feet per second (ft/s).

Front

How do you calculate distance using speed and time?

Back

Distance = Speed × Time.

Front

If a runner has a speed of 17.1 ft/s and runs for 3.5 seconds, what distance does she cover?

Back

60 ft.

Front

What is acceleration?

Back

Acceleration is the rate of change of velocity per unit of time, measured in meters per second squared (m/s²).

Front

How do you calculate acceleration?

Back

Acceleration = (Final Velocity - Initial Velocity) / Time.

Front

If a car slows from 190 m/s to 12 m/s in 20 seconds, what is its acceleration?

Back

-8.9 m/s².

Front

What is the difference between distance and displacement?

Back

Distance is the total path length traveled, while displacement is the straight line distance from the starting point to the endpoint.

Front

If Jerry walked 2 km to school and then 6 km to the park, what is his total distance?

Back

8 km.

Front

How do you convert grams to kilograms?

Back
