Newtons Laws Of Motion Flashcards
What is a normal force?
A perpendicular, equal but opposite force that presses two surfaces together.
Which direction does weight always act in?
Down
Distance with acceleration and time
X=(.5)at^2
How to find weight
W=mg
How to find Fp
Fp=mass times gravity times the sine of theta
How to find Fnormal
Mass times gravity times the cosine of theta
Newton’s First Law
An object at rest will remain at rest and an object in motion will remain in motion in a straight line at constant velocity unless acted upon by an outside force.
What is another name for Newton’s First Law of Motion?
The Law of Inertia
What is Inertia?
The reluctance of an object to change its state of rest or uniform motion
What is force?
A physical quantity that can affect the motion of an object.
What unit is force measured in?
Newtons (N)
Newton’s Second Law
F=ma
*Direction of the force is the same as that of the object’s acceleration
Newton’s Third Law
For every action there is an equal but opposite reaction
What is mass?
A measure of the quantity of matter in an object
What units are mass measured in?
Kilograms and slugs
