• Speed

Speed is defined as distance travelled per unit time. SI Unit is metre per second

• Velocity

Velocity is how fast displacement of the body is taking place. It is defined as the rate of change of displacement. It is nothing but speed along with providing information about the direction in which the body is moving. SI Unit is metre per second

• Acceleration

The rate of change in velocity is called acceleration. Acceleration is generally denoted by 'a'. Where, 'a' is acceleration, 'v' is final velocity, 'u' is initial velocity and 't' is time taken for change. SI Unit is meter per second square

• Torr

It is a unit of pressure.
