forces

Question 1

a push or pull one body exerts on another

Answer 1

force

Question 2

an object moving. keeps moving at the velocity an object at rest stays at rest unless acted upon by a net force

Answer 2

Newton’s first law

Question 3

the tendency of an object to resist any change in motion

Answer 3

inertia

Question 4

combination of forces that act on an object

Answer 4

net force

Question 5

every object exerts a force on every other object. felt as a pull

Answer 5

gravity

Question 6

the amount of matter or “stuff” an object has. measured in kilograms

Answer 6

Mass

Question 7

measure of force of gravity on an objects mass

Answer 7

weight

Question 8

” to every action there is an equal and opposite reaction force

Answer 8

Newton’s 3rd law of motion

Question 9

mass on the move. the force required to stop a moving object

Answer 9

momentum

Question 10

anything that’s thrown or shot through the air

Answer 10

projectile

Question 11

force acting toward the center of a curved or circular path

Answer 11

centripetal force

Question 12

opposes motion between two surfaces that are touching each other

Answer 12

friction

Question 13

resists getting an object moving( this is when objects are not moving)

Answer 13

static friction

Question 14

resists keeping an object moving( happens while it is moving)

Answer 14

kinetic friction

Question 15

Force = mass x acceleration

Answer 15

Newton’s second law
