Acceleration

Front

What is acceleration?

Back

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

Front

How is acceleration calculated?

Back

Acceleration is calculated using the formula: (final velocity - initial velocity) ÷ time.

Front

What is the unit of acceleration?

Back

The unit of acceleration is meters per second squared (m/s²).

Front

If an object accelerates from 0 m/s to 30 m/s in 5 seconds, what is its acceleration?

Back

6 m/s².

Front

What does a negative acceleration indicate?

Back

Negative acceleration indicates that an object is slowing down.

Front

What is the difference between speed and velocity?

Back

Speed is a scalar quantity that refers to how fast an object is moving, while velocity is a vector quantity that includes both speed and direction.

Front

What is uniform acceleration?

Back

Uniform acceleration occurs when an object's acceleration is constant over time.

Front

What is the formula for average acceleration?

Back

Average acceleration = (final velocity - initial velocity) ÷ time.

Front

A car accelerates from 10 m/s to 50 m/s in 4 seconds. What is the acceleration?

Back

10 m/s².

Front

What is instantaneous acceleration?

Back

Instantaneous acceleration is the acceleration of an object at a specific moment in time.
