Acceleration

Front

The SI unit for acceleration is

Back

m/s²

Front

A car starts from rest at a stop light and reaches 20 m/s in 3.5 s. Determine the acceleration of the car.

Back

5.7m/s²

Front

What is the formula to calculate speed?

Back

Speed = distance/time

Front

Can be measured in meters per second (m/s): Distance, Time, Speed, Acceleration

Back

Speed

Front

Does acceleration only occur when things speed up?

Back

False

Front

Determine where the car has no acceleration: A car shortly after a stoplight turns green, A car approaching a red light, A car with the cruise control set at 80 km/h, A car turning a curve at a constant speed.

Back

A car with the cruise control set at 80 km/h

Front

A roller coaster accelerates from an initial velocity of 6.0 m/s to a final velocity of 70 m/s over 4 seconds. What's the acceleration?

Back

16 m/s²

Front

A dog runs with an initial speed of 7.5 m/s on a waxed floor. It slides to a stop in 15 seconds. What is the acceleration?

Back

-0.5 m/s²

Front

Acceleration can be classified as: Speeding up, Slowing Down, Changing directions, All of the above

Back

All of the above
