Acceleration

Answer 1

A change in an objects velocity-speed up, slow down, change direction

Question 2

Force

Answer 2

a push or pull on a certain object

Question 3

balanced force

Answer 3

Forces that are equal in magnitude and going in separate directions- no change in motion, net force is 0

Question 4

unbalanced force

Answer 4

forces that are unequal and have a change in motion

Question 5

net force

Answer 5

sum of all forces acting on an object

Question 6

inertia

Answer 6

the tendency to resist a change in motion

Question 7

mass

Answer 7

Answer 8

Force of attraction between you and earth

Question 9

gravity

Answer 9

attractive force between any two objects

Question 10

friction

Answer 10

a force that opposes motion between two objects

Question 11

Law of inertia

Answer 11

An object in motion tends to stay in motion unless acted on by another force

Question 12

Law of acceleration

Answer 12

An object will travel the same way as the net force

Question 13

Law of action, reaction

Answer 13

For every action there is an equal but opposite reaction
