When liquid is transmitted is the press equal in all directions?

Yes

1 of 8

What is the formula for pressure(pa)?

Force (N)/ cross section area (m2)

2 of 8

How does the hydraulic system work?

The 1st piston is smaller with a smaller area so a small force is need to produce a pressure. This pressure is exert on the 2nd piston which is connected to the 1st piston, as the 2nd piston has a bigger area , so a bigger force is produced

3 of 8

Give 2 uses of a hydraulic system?

Car jacks and car braking systems

4 of 8

How is an object accelerating is it is constantly moving in a circle?

It is changing velocity as it is changing direction, so it is accelerating toward the centre of the circle it is traveling in (there must be a resultant force acting on the object)

5 of 8

What is a centripetal force?

This is the force which keeps the object moving

6 of 8

Give 2 examples of centripetal force:

Car going round a bend - friction between wheel and road, bucket swung on a rope - the force is the tension in the rope

7 of 8

Under what conditions is the centripetal force bigger?

When the object is going faster, the object has a bigger mass or the object is moving in a smaller circle
