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

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

Back

Its direction changes.

Front

The equation for finding average acceleration is ______.

Back

(final velocity - initial velocity) ÷ time

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

5.7 m/s²

Front

Define acceleration.

Back

Acceleration is the rate of change of velocity of an object with respect to time.

Front

What is the formula for acceleration?

Back

a = (final velocity - initial velocity) ÷ time

Front

What does a positive acceleration indicate?

Back

An increase in the velocity of an object.

Front

What does a negative acceleration indicate?

Back

A decrease in the velocity of an object, also known as deceleration.

Front

If an object is moving in a circular path at a constant speed, is it accelerating? Why?

Back

Yes, because its direction is changing.
