Law 1: Every object is still unless a force is caused and produces the objects acceleration. Force is caused by the movement that interacts with the object that was still.
Law 2: The relationship between mass, force, and distance, and how they are put in a formula to calculate a desired mass, or force, or distance.
Law 3:Every action and force caused to produce that action, there is always an opposite force caused when a normal force is caused, which makes the action balanced.

Science-Worksheet Questions
1. A) What is meant by doing work?
Using a force to move an object
B) What is meant by a machine?
A machine is anything which makes it easier to do work
2. A) Yes
B) Yes
C) Yes
D) No
Explain: Riding a bicycle, cleaning your teeth mowing the lawn, all include movement, and every movement contains force, while reading this page doesn’t cause movement to the paper because its still, producing no force at all.
3. Chemical energy needs to be supplied for the body so it may work properly, proper foods may supply that chemical energy
4. Machines are what they referred to because they make work easier, some work may not be done by humans bare hands, and so machines are created to make that work easier, they are also referred as Simple Machines.
5. Pulleys, Wedge, Levers.
P.81 Q1-4
1. A wheel and a Rope.
2. Using the pulley he can pull down the rope and lift up the car engine.
3. The chain transmits force into the back; the wheels are then turned by the force transmitted.
4. Low gear presents more wheels being used so less forced may be produced at the crankshaft but the same amount of force is being transmitted to move the wheels.

Machines, relation with work, force
Machines, have a great relation with work. Human beings use machines, simple machines, machines make work easier, making people create small force on their side, but great force is produced on the other side, causing the desire of the human beings work and job. Force is first created and done by the human, but through the machines mechanical privileges, creating great force and work on the other side, giving humans the advantage of achievement of what they are seeking.
