WHAT IS A FORCE?

FORCE

• It basically what allows an object to move.
• The force can make it pickup speed or slow down.
• The force is push or pull.
• Every thing on earth is affected by a force.
• Remember special forces dont change speed.

SIZE AND DIRECTION

• A small force cant move something too big.
• But a big force can obviously push something small
• The reason why is the items matter.
• If something has more matter than the force it wont move.

SPRING SCALES

• A spring scale measures how much force is on something
• The force is measured by newtons, after Issac Newton.

EXAMPLES

• The force of friction can slow down an object
• If you rub your eraser on paper it creates friction.
• Gravity will pull you downwards.
• If you're still on earth, gravity works.
• If your closer to the earth the force is stronger.

BALANCED AND UNBALANCED FORCES

• The net force is more than one force on an object.
• If the net force is 0 the forces are balanced.
• If the net force is more than 0 the object will move.
• If the inertia is stronger than the force it wont move.
• Acceleration will occur when the object begins to move.
