newton's laws

Question 1

newtons first law of motion:

Answer 1

when the forces acting on an object are balanced, the motion of the object stays the same

Question 2

in newtons first law, a stationary object

Answer 2

stays stationary

Question 3

in newtons first law, a moving object

Answer 3

does not get faster/slower/change direction

it travels at a constant speed in a straight line

Question 4

newtons 2nd law of motion:

Answer 4

when an unbalanced force acts on an object, the acceleration is directly proportional to the unbalanced force and inversely proportional to the mass of the object

Question 5

resultant force, mass, acceleration equation:

Answer 5

F = ma

Question 6

newtons third law:

Answer 6

every force causes an equal and opposite force

Question 7

when 2 objects interact, the force between them is

Answer 7

the same in both directions

Question 8

action-reaction forces occur

Answer 8

between 2 different objects

Question 9

in action-reactions, each force

Answer 9

acts on 1 of the objects
