Key Terms
Any push or pull that causes an object to move
What is force
Electrostatic can be charged either _____ or _____.
An object at rest will remain still unless one of these forces is applied to it.
Applied force, magnetism, gravity, static-electricity.
A force that happens when on object touches another. Example - opening a door or shooting a basketball.
Contact Force
A force that attracts masses
What is Gravity
When two charges or poles push apart.
What is repel/repulsion
Our weight is based on this force.
When an object is in motion, it is travelling in one direction. We can change the direction of the object in motion by applying a force to it. In sports, it is common to use this type of force.
Muscular Force/applied force/contact force.
A force that acts on an object without touching it. Example - when an apple falls from a tree
Non-Contact Force
A force that attracts. It refers to the attraction to iron, nickel, and cobalt. This force can push or pull an object depending on its poles.
What is Magnetism
When two charges or poles pull together.
What is Attract
There is no gravity in space. True or False.
False.
When an object slides over another object it starts to slow down because of this force.
What is friction.
Hitting a hockey puck into the net is _____________
Contact Force
When animals use their muscles to move an object
Muscular Force/applied
When objects repel or attract due to their electrical charge, it is called this.
What is Electrostatic Force.
Name 2 of the three main magnetic metals.
What are iron, nickel, and cobalt.
The magnitude of a vector arrow is shown by its ______?
What is size/length?
Water falling in a waterfall
Non-Contact force
The resistance of motion when two objects rub together.
Friction
Repeal and attract.
When like poles are facing eachother, this type of effect occurs.
What is Repulsion/repel.
Name two types of friction and give an example of each.
Air resistance/drag---falling through the air
Kinetic friction-sliding down a slide (surfaces rubbing together).
2 answers required---Rubbing your feet on a carpet
Attractive force when electrons jump from your negatively charged self to another object.
Friction--Contact force
Electrostatic---Non-Contact Force
