Pull
The word that describes that an object or part of an object changes position.

The force that pulls objects towards the Earth.
Gravity.
This force is caused by the attraction/repulsion of two poles. It is a non-contact force.
Magnetism.
When you jump into a pool, your body pushes down on the water and the water pushes up on you. What type of force is this?
Buoyancy.
Push
The six basic types of forces learned in our class.
Gravity, Friction, Muscular, Static Electric, Magnetic, Buoyancy.
The force that causes resistance when two objects or surfaces rub against each other.
Friction.
A force caused by two charged objects.
Static Electric force.
Pull
Moving a clothes line
Push and pull
When two objects have similar charges they _____ one another.
Repel.
Frictional force slows or stops movement when objects are ________ together.
Rubbed together.
What type of force does Static Electricity use?
Static Electric forces sometimes push and sometimes pull. Objects with different charges pull toward each other. Objects with the same charge push away from each other.
Buoyancy pushes in which direction. Upward or downward? Explain.
Upward.
Explain what happens to a kite in the air.
The wind pushes the kite as you run. You are pulling the kite as you run.
These two forces can sometimes push and sometimes pull.
Static Electric, Magnetic and/or Muscular forces.
The force of gravity only acts in one direction. True or false?
False. There is a force of gravity between any two objects, which could be in any direction.
How many poles do magnets have and what are their names?
Two. North and South.
Muscular force can sometimes use a pushing force and sometimes a pulling force. True or false?
True.
A push or pull that causes movement is a _____?
A force.
A force can change the __________, the ___________, or __________ an object.
A force can change the speed, the direction or stop an object.
What would happen if there was no such thing as gravity?
Which force does lightning produce?
