STUDY GUIDE

MOVEMENT is the change in position of a person or object
A FORCE can change the direction that an object is going.
A PUSH is a force that moves an object away from something
A PULL is a force that brings an object closer
POTENTIAL ENERGY is the energy "stored" in an object
KINETIC ENERGY is energy at work
TYPES OF FORCE: gravity, friction, upthrust/buoyancy, air resistance, turning, shearing, magnetic, spring etc.

SIMPLE MACHINES make work easier. WORK is completed when a force is applied and energy is applied. Simple machines either change the direction of force and/or the amount of force needed using a mechanical advantage!

An INCLINED PLANE is also known as a ramp. It makes work easier because you could push a heavy object up a ramp instead of picking it up
|
A LEVER is a bar on top of a fixed point. The fixed point is called the fulcrum.
|
A WEDGE is a pair of inclined planes placed back to back. It is used to force something apart.
|
|
A WHEEL AND AXLE is a wheel with a rod attached to its centre. The rod is called an axle. When the axle is turned, the wheel turns.
|
A SCREW is a cylinder with an inclined plane wrapped around it. A screw can be twisted into an object to connect it to another object
|
A PULLEY is a wheel with a groove in it and a rope in the groove. The groove helps to keep the rope in place.
