Pressure And Speed

Question 0

What’s the equation to work out the moment

Answer 0

Force x distance

Question 1

What is a moment.

Answer 1

The turning force around the pivot

Question 2

If there is a greater turning force (moment), what way will it I turn

Answer 2

Anti clockwise

Question 3

Greater on the right

Answer 3

Turn clockwise

Question 4

Speed

Equation

Answer 4

Speed equals distance divided by time

Question 5

Answer 5

Jhuvtyjfjyfvt

Question 6

States of motion

Name the 4

Answer 6

Acceleration
Deceleration
Constant
Stationary

Question 7

Do balanced forces change the motion

Answer 7

No

Question 8

What do unbalanced forces do

Answer 8

Change speed and direction of moving object

Question 9

Pressure

What would be the pressure if an object had a big area

Answer 9

Less pressure as less concentrated and more spread out

Question 10

What would be the pressure If the object had a small area

Answer 10

Higher pressure

Question 11

Streamline and friction

What does a streamline shape do

Answer 11

Pushes air particles away and makes it much quicker

Question 12

Draw a diagram to show a streamline shape

Answer 12

Question 13

What is air resistance

Answer 13

A force that drags an object back. It’s like friction.

Question 14

If you have a smaller air resistance, what effect would that have on the speed

Answer 14

Make it quicker and maybe streamline

Question 15

Friction

What are the good things about friction

Answer 15

Allows you to accelerate and decelerate

Safer

Question 16

What are the bad aspects of friction

Answer 16

Wastes transferred energy ( leg trying very hard to make the bike increase it’s speed but because of the friction some of the energy is lost and making the bicycle travel slower)

Question 17

Do q’s from sheet or rev guide for: pivots, pressure and speed
What’s the equation for pressure

Answer 17

Force divided by area
