states that an object at rest stays at rest, and an object in motion stays in motion at the same speed and in the same direction unless acted upon by an unbalanced force?
Newtons First Law (Law of Inertia)
a push or pull
a force
when an object is in contact with a surface is _______
Friction
A good sport that helps explain the movement of kinetic and potential energy, (often played on a field) is what?
Soccer
What two end of the magnet need to be close to each other in order to repel?
Either
North and North ends
Or South and South ends
states that for every action, there is an equal and opposite reaction
Newtons 3rd Law
a force in which objects do NOT need to be touching!
Non-Contact or Feild force.
Friction produces ____
Heat
stored energy
potential energy.
What two ends ends the magnet need to face each other in order to attract
Positive with the Negative side
Or North and South ends.
talks about mass and acceleration. Mass x acceleration = force.
Newtons 2nd Law
to be a balanced force both sides must be pulling and pushing with __ Newtons
0
a friction-like force that opposes forward motion in a fluid
a drag
a form of energy that an object or a particle has by reason of its motion
Kinetic Energy
A rectangular magnet that has one south and one north end is called a ___ magnet
A Bar Magnet
Newton's laws of motion are three physical laws that describe the relationship between the motion of an object and the ______ acting on it.
Forces
when the push or pull has more newtons on either side it is called a ____________ force
unbalanced force.
Resists the initiation of motion between two resting surfaces.
Static Friction
Type of energy within a system that's created by the random motion of molecules and atoms. Example:Boiling water on the stove
Thermal Energy
area in which an object experiences a force.
a feild
The formula for Newtons Second law is _____
F=ma
name of what is happening if the amount of newtons from the push and the pull is equal
A good example of the use of friction of everyday use is what? (a piece of clothing you were everyday.)
Your shoes
Energy that is stored in the bonds of chemical compounds, like atoms and molecules. Ex: Coal, Gasoline, Batteries
Chemical Energy
Susie has a piece of metal and is trying to figure out which of the other metals she has are true magnets.
1- The first one she trys repels from the metal
2- The second one just falls and will not stick to the metal
3- The third and last sticks to the metal and attracts
Which of the metals that Susie tested are true magnets? (1, 2 or 3) There can be more than one number
Numbers 1 and 3
