WEDGE

IT HAS 2 SLANTED SIDES THAT END IN A SHARP EDGE. IT IS USED TO DIVIDE ONE OR TWO PARTS AND HELP US TO MAKE WORK EASIER

WHEEL AND AXLE

MADE OF A ROUND OBJECT, A WHEEL, ATTACHED TO A POST CALLED AXLE

LEVER

IT IS A BAR THAT RESTS ON A SUPPORT. IT IS USED TO LIFT THINGS

SCREW

IT IS AN INCLINED PLANE WRAPPED AROUND A CENTER POST

PULLEY

DECREASE THE AMOUNT OF FORCE THAT IS NEEDED

INCLINED PLANE

IT IS A SLANTED SURFACE THAT CONNECTS A LOWER LEVEL WITH A HIGHER LEVEL

CHOOSE THE LEVER

Next

Right answer!

A lever is a simple machine made of a rigid beam and a fulcrum. The effort (input force) and load (output force) are applied to either end of the beam. The fulcrum is the point on which the beam pivots. When an effort is applied to one end of the lever, a load is applied at the other end of the leve

CHOOSE THE INCLINED PLANE

Next

Right answer!

An inclined plane, also known as a ramp, is a flat supporting surface tilted at an angle, with one end higher than the other, used as an aid for raising or lowering a load.

CHOOSE THE SCREW

Next

Right answer!

A screw is a mechanism that converts rotational motion to linear motion, and a torque to a linear force. It is one of the six classical simple machines.

CHOOSE THE WHEEL AND AXLE

Wronganswer

Next

Right answer!

The wheel and axle is a machine consisting of a wheel attached to a smaller axle so that these two parts rotate together in which a force is transferred from one to the other.

CHOOSE THE WEDGE

Next

Right answer!

A wedge is a triangular shaped tool, and is a portable inclined plane, and one of the six classical simple machines. It can be used to separate two objects or portions of an object, lift up an object, or hold an object in place

CHOOSE THE PULLEY

Next

Right answer!

A pulley is a wheel that carries a flexible rope, cord, cable, chain, or belt on its rim. Pulleys are used singly or in combination to transmit energy and motion.

WORK

THE USE OF A FORCE TO MOVE AN OBJECT ACROSS A DISTANCE

WHAT IS WORK?

A. IT IS WHEN YOU USE YOUR FORCE TO MOVE AN OBJECT

B. DO DIFFICULT THINGS

C. THINK A LOT

D. BEING A DOCTOR OR TEACHER

WORK IS WHEN YOU USE YOUR FORCE TO MOVE AN OBJECT

CHOOSE WHAT WORK IS

Next

Right answer!

Work is the energy transferred to or from an object via the application of force along a displacement. In its simplest form, it is often represented as the product of force and displacement.
