Acceleration

Front

What is acceleration?

Back

Acceleration is the rate of change of velocity of an object. It can involve an increase or decrease in speed, or a change in direction.

Front

How can acceleration be zero?

Back

Acceleration is zero when an object is moving at a constant speed in a straight line.

Front

Does changing direction constitute acceleration?

Back

Yes, changing direction is a form of acceleration, even if the speed remains constant.

Front

What is the difference between speed and acceleration?

Back

Speed is the rate at which an object covers distance, while acceleration is the rate of change of speed.

Front

Can an object accelerate while moving at a constant speed?

Back

No, an object cannot accelerate if it is moving at a constant speed; it must change its speed or direction.

Front

What does a negative acceleration indicate?

Back

Negative acceleration, or deceleration, indicates that an object is slowing down.

Front

What is uniform acceleration?

Back

Uniform acceleration occurs when an object's velocity changes at a constant rate.

Front

What is the formula for calculating acceleration?

Back

Acceleration (a) = (Final velocity (v) - Initial velocity (u)) / Time (t).

Front

What is an example of positive acceleration?

Back

A car speeding up from 20 km/h to 60 km/h is an example of positive acceleration.

Front

What is an example of negative acceleration?

Back

A car slowing down from 60 km/h to a stop is an example of negative acceleration.
