Presentation Transcript

What is Energy?

- The ability to do work
- Each time work is done, energy is transferred from one object to another
- Work & energy are so closely related that they are both expressed in Joules (J)

What is Kinetic Energy?

- Kinetic Energy = ENERGY OF MOTION
- All moving objects have kinetic energy
- Objects with kinetic energy can do work

Example of Kinetic Energy

- Example: A hammer moves & hits a nail The downward swinging force pushes the nail down = work being done

How Do You Calculate Kinetic Energy?

- KE = mv2

m=mass

v=velocity

**Velocity has a HUGE affect on kinetic energy

What is Potential Energy?

- Potential Energy = STORED ENERGY
- This is the energy an object has because of position or shape.

Example of Potential Energy

- Example: Work is done on a bow to stretch it out and change its shape

How Do You Calculate Potential Energy?

- Gravitational potential energy depends on an object’s weight & height above the Earth’s surface.
- PE = weight x height

What is Mechanical Energy & How Do You Calculate It?

- Total energy of motion & position
- ME = KE + PE
