TOPIC: Energy AIM: How can energy be different?

2 Types Of Energy 1. Kinetic Energy energy of motion

Kinetic Energy facts: The faster/greater the velocity of an object the greater the Kinetic energy of the object in motion

The larger/greater the mass of an object the greater the Kinetic energy the object in motion

2

Example m= 2 kg v= 2m/s KE = ? KE = mv 2 2 KE = 2 x KE = 2 x 4 2 KE = 4 J

Example m= 10kg v= 3m/s KE = ? KE = mv 2 2 KE = 10 x KE = 10 x 9 2 KE = 45 J

Example m= 5kg v= 1m/s KE = ? KE = mv 2 2 KE = 5 x KE = 5 x 1 2 KE = 2.5 J

2.Potential Energy stored energy that is not moving/ not working

Examples: 1. Stretched rubber band posseses a lot of Potential Energy When you let the rubber band go the PE is released

2. Unlit match the PE is stored until the match is lit

The massive ball of a demolition machine and the stretched bow possess stored energy of position = Potential Energy

REVIEW: KINETIC OR POTENTIAL ENRGY?

Gravitational Potential Energy The potential energy that depends on height The greater the weight of the object the greater the Grav. Pot. Ener. will be

The greater the height of the object the greater the Grav. Pot. Ener. will be

Example: Person on a 3m high diving board has more GPE than person on 1m high board

GPE = weight x height Example: What is the GPE of a 780 N diver on a diving board that is 10 m high? GPE = w x h = 780N x 10m GPE = 7800 J

Example: What is the GPE of a 320 N diver on a diving board that is 5 m high? GPE = w x h GPE = 320N x 5m GPE = 1600 J

Example: Who has a higher GPE ? A) 300N diver on a 3m diving board B) 75N painter on an 8m ladder C) 500N diver on a 2m diving board

Do Now: If a 70N squirrel is on a branch that is 4 meters above the ground, what is the gravitational potential energy? Show all work!!!

TOPIC: Energy AIM: How does energy change from one type to another?

Energy Conversion Change of energy from 1 type to another KE  PE PE  KE

Example: Throwing a ball into the air V = 0 m/s PE  KE V V KE  PE V = 0 m/s V PE  KE PE = max KE = 0 J PE = max KE = 0J

KE = max PE = max PE = 0 J Speeding up Slowing down V = 0m/s V = max KE = 0 J PE  KE KE  PE

As the car loses height, it gains speed. PE is changed into KE. The sum of the KE and PE is constant. It never changes.

On the platform: PE = max KE = 0 Joules During the jump: KE is increasing PE is decreasing In the water: KE = 0 Joules PE = max youtube.co m/watch?v =vl4g7T5g w1M PE  KE
