Acceleration

Front

What is acceleration?

Back

Acceleration is defined as the change in velocity divided by the time interval.

Front

What is the metric unit for acceleration?

Back

The metric unit for acceleration is m/s².

Front

How do you calculate acceleration?

Back

Acceleration can be calculated using the formula: a = (final velocity - initial velocity) / time.

Front

What does a positive acceleration indicate?

Back

A positive acceleration indicates that an object's velocity is increasing.

Front

What does a negative acceleration (deceleration) indicate?

Back

A negative acceleration indicates that an object's velocity is decreasing.

Front

What happens to acceleration when an object moves at a constant speed in a circular path?

Back

The object experiences acceleration due to the change in direction, even though its speed remains constant.

Front

If a car accelerates from 20 m/s to 60 m/s in 4 seconds, what is its acceleration?

Back

The acceleration is 10 m/s².

Front

What is the relationship between acceleration and force according to Newton's second law?

Back

According to Newton's second law, acceleration is directly proportional to the net force acting on an object and inversely proportional to its mass (F = ma).

Front

What is the effect of mass on acceleration?

Back

An increase in mass results in a decrease in acceleration if the same force is applied.

Front

How can you determine if an object is accelerating?

Back

An object is accelerating if its velocity is changing, which can be observed through changes in speed or direction.
