Acceleration test

Front

What is acceleration?

Back

Acceleration is the rate of change of velocity of an object with respect to time. It is a vector quantity, meaning it has both magnitude and direction.

Front

What is the formula for average acceleration?

Back

Average acceleration (a) is calculated using the formula: a = (final velocity - initial velocity) / time.

Front

If a roller coaster car's speed increases from 4 m/s to 22 m/s in 3 seconds, what is its average acceleration?

Back

6 m/s².

Front

How do you convert km/h to m/s?

Back

To convert km/h to m/s, divide the speed by 3.6.

Front

What is the average acceleration of a car that accelerates from rest to 70 km/h in 7 seconds?

Back

2.7 x 10^-3 km/s².

Front

What is the relationship between distance, speed, and time?

Back

The relationship is given by the formula: distance = speed x time.

Front

If a bike travels 200 meters with a constant acceleration of 1.20 m/s² and reaches a final speed of 25 m/s, what was its initial speed?

Back

12 m/s.

Front

What is the formula to calculate speed?

Back

Speed (S) = distance (d) / time (t).

Front

How long does it take for an object moving at 16 m/s to travel 960 meters?

Back

1 minute.

Front

What is a vector quantity?

Back

A vector quantity is a physical quantity that has both magnitude and direction, such as velocity and acceleration.
