Newton's Laws and Application of Newton's Laws

Question 1

weight Fg

Answer 1

the gravitational force the Earth exerts on any
object on or near its surface

Question 2

normal force FN

Answer 2

the perpendicular force exerted by a
surface on an object in contact with it

Question 3

frictional force due to a surface Ff

Answer 3

the force that
opposes the motion of an object and acts parallel to the surface
with which the object is in contact

Question 4

Newton’s first law

Answer 4

An object continues in a state of rest or uniform (moving with constant) velocity unless it is acted upon by a net or resultant force

Question 5

inertia

Answer 5

the property of an object that causes it to resist a change in its state of rest or uniform motion

Question 6

Newton’s second law

Answer 6

When a net force, Fnet, is applied to an object of mass, m, it accelerates in the direction of the net force. The acceleration, a, is directly proportional to the net force and inversely proportional to the mass

Question 7

Newton’s third law

Answer 7

When object A exerts a force on object B, object B simultaneously exerts an oppositely directed force of equal magnitude on object A

Question 8

Rough, Rest and constant velocity/speed and a random tip respectively

Answer 8

Friction, velocity is = 0 and acceleration are = 0 it is better to use Fg’s components when addressing a force question

Question 9

When asked for the distance what formulas can I use

Answer 9

fg=ma then Vf^2=vi^2+ 2ax

or

Wnet=Fnetxcosx

Question 10

About the words dropped

Answer 10

The initial velocity of an object drop = initial velocity of the object not in free fall(only acted on by gravity) and always shows direction
