1

What are the properties of a liquid?

virtually incompressible

all the pressure in a liquid is transmitted equally in all directions

2

How are force multipliers achieved?

The use of different cross-sectional areas on the effort and load side of a hydraulic system enables the system to be used as a force multiplier

3

What direction does an object moving in a continuous circle accelerate?

it accelerates towards the centre of the circle

the acceleration changes in the direction of the motion of the body, not its speed

4

What causes the acceleration of the object moving in a circle?

the resultant force causing this accelerated is called the centripetal force

it is always directed towards the centre of the circle

5

How does centripetal force increase?

increases as:

the mass of the object increases

the speed of the object increases

the radius of the object increases
