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 formula for calculating acceleration?

Back

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

Front

If a car accelerates from 0 m/s to 20 m/s in 4 seconds, what is its acceleration?

Back

5 m/s²

Front

What does a positive acceleration indicate?

Back

A positive acceleration indicates that an object is speeding up.

Front

What does a negative acceleration (deceleration) indicate?

Back

A negative acceleration indicates that an object is slowing down.

Front

What is constant speed?

Back

Constant speed means an object covers equal distances in equal intervals of time.

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

What is the unit of acceleration in the SI system?

Back

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

Front

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

Back

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