What is friction?
Friction is the procedure of two surfaces rubbing against each other.
Friction acts in what direction?
Friction acts in the opposite direction of the object's motion.
What is friction measured in?
The strength of friction depends on what two factors?
It depends on the type of surface and the pressure of the friction.
What are the four main kinds of friction?
Fluid friction, Sliding friction, Rolling friction, Static friction.
Which kind of friction requires more force to overcome, rolling or sliding friction?
What two things does gravity depend on?
It depends on mass and distance.
What is gravity measured in?
It is measured in newtons.
What is gravity?
Gravity a force that pulls objects towards each other.
What two things does friction depend on?
Friction depends on the push or pull on two surfaces and the types of surfaces involved.
What is static friction?
Static friction is friction that acts on objects that are not moving.
What is sliding friction?
Sliding friction is when two solid surfaces slide over each other.
What is rolling friction?
Rolling friction occurs when an objects rolls over a surface.
What is fluid friction?
Fluid friction is when a solid friction moves through a fluid.
What kind of friction occurs when you're skateboarding?
What kind of friction occurs when your surfing?
What is terminal velocity?
Terminal velocity is when force of air resistance equals the weight of the object.
What is air resistance?
Air resistance is when falling objects through air experience a type of fluid friction.
What is weight
Weight is the measurement of gravitational force exerted on an object.
What is mass?
Mass is the amount of matter in an object.
