Answer 12

displacement, velocity, force, acceleration

Question 12

what is instantaneous speed

Answer 12

speed at any given point in time

Question 13

what is acceleration

Answer 13

a change in speed or velocity

Question 14

units for acceleration

Answer 14

ms^2

Question 15

a force is (examples)

Answer 15

push or pull, acts on an object, is a vector, contact or long range

Question 16

what is newtons first law

Answer 16

any obkect that is at rest will remain at rest, and moving object with stay at motion unless an onbalanced force acts upon it.

Question 17

what is newtons third law

Answer 17

FOR EVERY ACTION FORCE, THERE IS AN EQUAL AND OPPOSITE REACTION FORCE.

Question 17

what is newtons second law

Answer 17

acceleration depends on the net force on the object and the mass of the object
