Force Basics
A push or pull on an object
What is a force?
A force that requires objects to touch
What is a contact force?
Unbalanced Forces can change this of an object
What is the motion?
The 3 types of friction are
What is Static, Kinetic and Rolling friction.
The amount of matter in an object
What is mass?
Forces are measured in this unit
What is a Newton?
A force that acts without touching
What is a non-contact force?
Forces are balanced when net force equals this
What is 0
Order types of friction from strongest to weakest
What is Static, Kinetic, Rolling
The force of gravity on an object
What is weight?
Forces are vector quantity's What does this mean?
Forces have magnitude and direction?
A pulling force through a rope or string
What is tension force?
The overall force acting on an object
What is the net force?
Friction affects motion by...
What is slowing the object down.
The unit for mass is... The unit for weight is...
What is kg? What is N
The force that pulls objects toward Earth
What is gravity?
A force that opposes motion
What is friction?
Net force is found by doing this to forces
What is Adding forces acting in the same direction and subtracting those in the opposite direction?
Deja pushes on a box with all of her force but it doesn't begin moving. This is because of what kind of friction?
What is Static friction?
Weight can change when this changes
What is gravity / location (planet)
The force that supports an object on a surface
What is normal force?
Air resistance is this type of force
What is friction?
An object is sitting on the table. Draw a force diagram for the forces acting on the object.
This causes friction between surfaces
Determine the mass and the weight of this object on Earth. Then calculate the Weight on moon (1.6 m/s2)
(First team to finish gets 200 extra points.)
(all teams get points if answer is correct)
Mass in Kg 0.291-0.297kg
Earth Weight in N 2.85N-2.91N
Moon Weight 0.46 N -0.47 N
