Net force
The sum or Difference of the forces acting on an object.
Friction
A force acting against an object moving that tries to slow that object down.
how can magnets attract(which pole need to be where)?
North and south or south and north together.
Tom is pushing a box 40N to the right.
Jerry is pushing that same box 35N to the left.
What is the net force,
and which direction will the box move?
5N to the right
What energy helps us move?
Mechanical energy.
Gravity
A force between any 2 thing with mass that pulls them together.
Non-contact force
any force that does not need to touch to move
When 2 people are pushing a box from the SAME side and at the SAME direction, how to you find the net force?
2 people are pushing a box 50N to the left
1 person is pushing that same box 100N to the right
what is the net force,
and which direction will the box move
What is potential energy?
The energy that can be used.
Normal force.
Basically a balanced force.
Applied force.
Forces being applied to something.
What class are we in right now?
Science I think.
Bob is pulling a box with 50N
friction is pulling backa 5N
How much force is actually applied.
45N
What is kinetic energy?
The energy being used.
Potential energy
Energy that has the potential or can move.
Kinetic energy
The energy being used
20 squared
400, also that´s how many points you are getting lol
10 people are pushing a box at the force of 10N each
friction is opposing them at 5N per person
what is the net force direction not needed
50N
what is gravitational potential energy.
Potential energy that is stored because of gravity.
Magnetism
The attractive, non-contact force that attracts or repels certain metals together.
Contact force
(And for and extra 100 points, name 2 examples)
A force that needs to be touching for it to work. Friction, Applied, Ect.
I don't know what to put here so free points
if you said no then you get the points
2 teams of 3 people are playing tug of war
joe and sally are on the same team pulling at 100N each
sam and peter are on the same team pulling at 125N each
jerry is on Sam´s team and normally pulls at 200N, but he is tired so he is pulling half of his normal
luke is pulling at double the force of peter
what is the net force, direction not needed
100N
What is chemical potential energy?
Potential energy stored in chemicals like batteries or a soda you shook up.
