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

What is the formula for calculating acceleration?

Back

The formula for acceleration (A) is A = (final velocity - initial velocity) / time.

Front

What does a negative acceleration indicate?

Back

Negative acceleration, also known as deceleration, indicates that an object is slowing down.

Front

What is initial speed?

Back

Initial speed is the speed of an object at the start of a time interval.

Front

Can an object accelerate while moving at a constant speed?

Back

Yes, an object can accelerate if it changes direction while maintaining a constant speed.

Front

What is the unit of acceleration?

Back

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

Front

If a car is moving at a constant speed of 80 km/h, is it accelerating?

Back

No, the car is not accelerating because its speed is constant.

Front

How do you calculate the time taken for an object to accelerate?

Back

Time can be calculated using the formula t = (final velocity - initial velocity) / acceleration.

Front

What is the acceleration of an object that comes to a stop?

Back

The acceleration is negative, indicating deceleration, and can be calculated using the formula A = (0 - initial velocity) / time.

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.
