The amplitude of a wave is the: a maximum displacement from the position of rest.

• maximum displacement from the position of rest

• minimum distance before a wave starts to repeat itself

• number of cycles made in 1 second.

The rate of change of distance with respect to time is termed:

• velocity

• acceleration

• momentum

What is the approximate value of gravitational acceleration at sea level?

• 10ms-1

• 10ms^-2

• 100m/s

The scientific unit of Angular velocity is measured in :

• radians per second

• degrees per second

• revolutions per minute

When a rotating shaft is caused to vibrate because of poor balancing the vibration pattern is called a:

• damped wave

• standing wave

• refracted wave

If the frequency and amplitude of an applied force is equal to the vibrating frequency of a device then:

• the device will resonate

• the device will appear to stop instantly

• no change in the device's movement will be seen

Mass is defined as the:

• force experienced on a body when accelerating

• quantity of matter in a body

• quantity of matter per unit volume

Inertia of a body is the:

• energy stored in a body due to it's momentum

• instantaneous transfer of momentum on impact

• resistance of a body to a change in direction

The derived SI unit expressed as: kilogram metre per second per second is known as:

• the Joule

• the Newton

• Momentum

Power is:

• the amount of energy converted per second

• the amount of work done

• measured in joules
