Calculating Acceleration

Front

What is acceleration?

Back

Acceleration is the rate of change of velocity of an object with respect to time. It is measured in meters per second squared (m/s²).

Front

How do you calculate acceleration?

Back

Acceleration (a) can be calculated using the formula: a = (final velocity - initial velocity) / time.

Front

What is the unit of acceleration in the metric system?

Back

The unit of acceleration in the metric system is meters per second squared (m/s²).

Front

Convert 90 km/h to m/s.

Back

90 km/h is equal to 25 m/s (90 km/h ÷ 3.6 = 25 m/s).

Front

What is the acceleration of a fighter jet that reduces speed from 153 km/h to 0 km/h in 2 seconds?

Back

The acceleration is -76.5 km/h/s (deceleration).

Front

What is the acceleration due to gravity on Mars?

Back

The acceleration due to gravity on Mars is approximately 3.71 m/s².

Front

How many meters are in a kilometer?

Back

There are 1000 meters in a kilometer.

Front

How many seconds are in one hour?

Back

There are 3600 seconds in one hour.

Front

What is the formula for converting km/h to m/s?

Back

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

Front

If a car accelerates from 0 to 90 km/h in 7.5 seconds, what is its acceleration?

Back

The acceleration is 12 km/h/s.
