Physics Acceleration

Front

A golf ball accelerates off a tee at 15m/s², changing its velocity from 0m/s to 50 m/s down the fairway. How long did it take the golf ball to accelerate?

Back

3.3 seconds

A box sliding down an inclined plane attains a velocity of 27 m/s in 3 seconds from rest. Find the acceleration.

Back

9 m/s²

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 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

Acceleration is defined as the CHANGE in

Back

velocity divided by the time interval

Front

Why does a car accelerate as it rounds a corner at a constant speed?

Back

Its direction changes

Front

Does acceleration only occur when things speed up?

Back

False

Determine where the car has no acceleration:
- A car speeds up after a stoplight turns green.
- A car slows down as it approaches a red light.
- A car with the cruise control set at 80 km/h going down a straight highway.
- A car turning a curve at a constant speed.

Back

A car with the cruise control set at 80 km/h going down a straight highway.
