1st law
newtons first law
is a body at rest remains at rest, and a body in motion remains in motion
The force that attracts an object toward the center of the earth
Gravity
The SI unit of force is this.
Newton
This type of friction has to do with water or something falling through the air
Fluid Friction
The reluctance of any body to change its state of motion
What is inertia?
A box is being pushed to the right across the floor. What is the force that opposes this motion?
Friction
Newton's third law states
Any action has an equal and opposite reaction.
This type of friction has to do with something gliding across another surface. Kind of like an ice skater on ice.
Sliding Friction
Which law talks about an object at rest or moving with constant velocity remaining in that state unless a non 0 external force acts on it
first law
A bowling ball collides with a set of bowling pins (at rest) with a force of 15N. What is the force the pins exert on the bowling ball.
15n
All forces act in pairs called action and Reaction forces.
What is Newton's third law say?
This friction has to do with an object that is sitting completely still
Static Friction
An object at rest has this velocity
0
This property of matter increases with its mass.
inertia
Newtons law of action and Reaction
3rd law
This type of friction occurs between a tire of a moving car and the road.
Rolling Friction
A change in velocity (speed and/or direction) is known as
acceleration
Which forces act upon a skier going down hill?
Air resistance, gravitational, normal, frictional
What is the formula to calculate speed
S=D/T
Name each of the types of friction in any given order.
Rolling, Sliding, Static, Fluid
