Acceleration

Front

What is acceleration?

Back

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

Front

What is the unit of acceleration?

Back

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

Front

What does a negative acceleration indicate?

Back

Negative acceleration indicates deceleration, meaning the object is slowing down.

Front

What is constant speed?

Back

Constant speed means an object is moving at the same speed over time, with no acceleration.

Front

What is the formula for calculating acceleration?

Back

Acceleration (a) = (final velocity - initial velocity) / time.

Front

If an object is at rest, what is its acceleration?

Back

If an object is at rest, its acceleration is 0 m/s².

Front

What happens to an object's speed during acceleration?

Back

During acceleration, an object's speed increases.

Front

What happens to an object's speed during deceleration?

Back

During deceleration, an object's speed decreases.

Front

What is the difference between speed and velocity?

Back

Speed is a scalar quantity (magnitude only), while velocity is a vector quantity (magnitude and direction).

Front

How can you tell if an object is accelerating from a graph?

Back

An object is accelerating if the slope of the velocity-time graph is not constant.
