Topics 1.10 and 1.11 - Circular Motion and Hydraulics

What happens when an object moves in a circle?
When an object moves in a circle it continuously accelerates towards the centre of the circle, this changes the direction of motion of the body but not it's speed
1 of 6
What is the name of the resultant force here?
The resultant force causing this acceleration is called the centripetal force, it is always directed towards the centre of the circle
2 of 6
What can increase the centripetal force of an object?
An increase in the mass of the object, An increase in the speed of the object, A decrease in the radius of the circle
3 of 6
What is virtually incompressible?
Liquids are virtually incompressible, and the pressure in a liquid is transmitted equally in all directions
4 of 6
What is the relationship between pressure, force and cross-sectional area?
Pressure = Force ÷ Cross-Sectional Area
5 of 6
How can a system be used as a force multiplier?
The use of different cross-sectional areas on the effort and load side of a hydraulic system can enable it to be used as a force multiplier
