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?

Back

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

Front

If an object is at rest and starts moving, what is its initial velocity?

Back

The initial velocity of an object at rest is 0 m/s.

Front

What does a negative acceleration indicate?

Back

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

Front

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

Back

Time can be found using the formula: time = (final velocity - initial velocity) / acceleration.

Front

What is the acceleration of a box sliding down an inclined plane if it reaches 27 m/s in 3 seconds?

Back

The acceleration is 9 m/s².

Front

A dog slides to a stop from 7.5 m/s in 15 seconds. What is its acceleration?

Back

The acceleration is -0.5 m/s².

Front

How do you determine the rate of acceleration from speed and time?

Back

Rate of acceleration can be determined by dividing the change in speed by the time taken.

Front

What is the formula for calculating final velocity?

Back

Final velocity (v) can be calculated using the formula: v = initial velocity + (acceleration × time).
