 In physics, force is anything that can cause a body of mass is accelerating. Forces is defined as a pull or push. The forces is said to push such as a boost at the time we hit or kicked. At the time we take water from wells, we also provide force, but this force of pull. Effect of force against objects can be used in a variety of equipment, such as appliance arrows, slingshots, car springs, and other tools are aplenty. In everyday life we know there are several different forces including: muscle force (in humans), the spring force (spring car), magnetic force (compass, etc..) and the style of the machine(car / motorcycle).

 There are about seven forces. Friction force, muscle force, spring force, electric force, the force machine, the force of gravity, and magnetic force.  These force can make things attracted or pushed.

 Is there a tool to measure the force? There! The device is called a dynamometer!

 Forces can make things: 1. Change: shapes, size, place 2. Move 3. etc.

 Friction force is where a surface of an object meet with one surface of an other object. We can make this force enlarged or reduced.  Example of this force: - When the shoe touches the floor. This is a friction force due to the shift that caused a friction force.

 Muscle force can we encounter daily. muscle fo rce is one of the forces we produce from within our own bodies.  Example of this force are: - A weight lifter can lift weights with a certain weight. - Someone who was riding a bicycle. - People who are rowing a boat. The examples above are examples of muscle force.

 Spring force is used humans to produce certain things for example in the motor vehicle that is in car seats, car springs, scokbreker, etc.

 This style is owned by objects that are electrically charged such that the force generated by the friction of hair on the comb which will generate electricity while.

The force machine used in heavy vehicles to do the heavy work for example in car scraper, bulldozer, etc.

These gravitational forces generated by the earth because of gravity. For example objects falling to earth, airplanes, etc. Gravity is also not made by humans but has been there all along. But people realized the gravity for years after the AD. Who learn /discover about gravity is Sir Isaac Newton.

 Utilization of magnetic force are found in children's pencil cap, close the fridge, etc.. No need to search all the way in which there is a magnet. In the world contained a very large magnet, especially in the north pole. So that a compass needle will always point to the north. There are three ways to make a magnet that is 'induction', 'rubbing', and 'electromagnetic'. And to make a magnet how something missing that contain magnets should slam, trampled, etc.

 What can make a magnet?  Give five examples of the style of muscle!  Write all forces!!!  Does the world contain a magnet? Where exactly is the magnet in the world!  What tools to measure force?  Who discovered the gravity?  What causes friction force? ANSWER IT IN YOUR BOOK

 Prepare a bar magnet, paper, and a few grains of sand. Fold paper in half. Tuck thesand in it. Then put the paper on the desk surface. Then invite your friends to see whathappens. Then silently with out someone who knows, you move the bar magnet from under the table for sand in the paper will move. After that ask what happened to your friend!
