Question

part 3 - newton’s laws of motion

1. newton’s first law of motion

● newton’s first law of motion is also known as the law of
● newton’s first law says that
○ an object at rest tends to stay at and an object in motion tends to stay in
with the same velocity and in the same direction unless acted upon by an
(net) force.”
● is an object’s resistance to change in motion.
● what property of an object determines how much inertia it has?
● which of the following has more inertia?
○ bowling ball or tennis ball
○ hammer or feather

1. newton’s second law of motion

● newton’s second law of motion is also known as the law of
● newton’s second law says that
○ the acceleration of an object is directly proportional to the net acting on the object, and
inversely proportional to the of the object.
● the greater the force that is applied to the object, the (greater, lesser) the acceleration.
● the lesser the force that is applied to the object, the (greater, lesser) the acceleration.
● if the same force is applied to an object with a large mass, it will have a (greater, lesser) acceleration.
● if the same force is applied to an object with a small mass, it will have a (greater, lesser) acceleration.
● the equation that is used to solve second law problems is
○ what do each of the variables mean?
f = m = a =

1. newton’s third law of motion

● newton’s third law of motion is also known as the law of
● newton’s third law says that
○ for every force, there is an equal and opposite force.”
● newton’s third law states that forces must always occur in
● listed below are action forces. tell the reaction force.
○ your bottom pushing on your desk seat-

Explanation:

Newton's first law is the law of inertia, stating objects at rest stay at rest and in - motion objects stay in motion with the same velocity and direction unless a net force acts. Inertia is related to mass. For the second law (law of acceleration), acceleration is proportional to net force and inversely to mass, with formula F = ma (F is force, m is mass, a is acceleration). The third law (law of action - reaction) says for every action force there is an equal and opposite reaction force, and forces occur in pairs.
