Physics/Biology Term 4

Question 1

What is energy

Answer 1

Energy is the ability to do work - is measured in Joules (J)

Question 2

Answer 2

Kinetic (moving object)
- Thermal
- Magnetic
- Electrical
- MECHANICAL

- Gravitational
- Elastic
- Nuclear
- Chemical

kind monkeys thoroughly enjoy music. pouting giraffes never even clean.

Question 3

What can one joule do?

Answer 3

Lift 1kg 10cm and lift 10kg 1cm

Question 4

How do you calculate potential energy

Answer 4

E=mgh

Question 5

How do you calculate kinetic energy

Answer 5

E=0.5mv²

Question 6

What is work

Answer 6

the force applied over a distance

Question 7

How do you calculate work?

Answer 7

W=Fd
work= force x displacement

Question 8

What is work is done

Answer 8

Energy transferred

Question 9

What is a force and different types of force

Answer 9

A force is a push, pull or twist in any direction. Measured in Newtons (N)
Contact
- push
- pull
- tension
- buoyancy
- friction
- air resistance

Non-Contact
- magnetic
- gravitational
- electrostatic

can peter pull together baking flourless apple rubarb?
no can’t gavin might explode

Question 10

How do you calculate force?

Answer 10

F=ma
Force= mass x acceleration

Question 11

How to calculate speed/velocity

Answer 11

v=d/t
Velocity = distance/time
Measured in m/s

Question 12

How to calculate acceleration

Answer 12

A=△V / △T
Acceleration = change in velocity/change in time
