47
Q

an object with remain at rest or in motion unless acted on by an unbalanced force

A

Newton’s first law (law of inertia)

48
Q

property of an object to resist both the initiation of motion and change in motion

A

inertia (summation of forces = 0)

Q

acceleration of an object is proportional to the unbalanced forces acting on it and inversely proportional to the mass of the object

A

Newton’s second law (law of acceleration) (a = F/m)

Q

for every action there is an equal and opposite reaction

A

Newton’s third law (reaction forces)
