Forces

Question 1

a push or a pull one body exerts on another

Answer 1

what is a force

Question 2

an object moving at a constant velocity keeps moving at that velocity- an object at rest stays in rest unless acted upon

Answer 2

newtons 1st law

Question 3

the tendency of an object to resist any change in motion

Answer 3

inertia

Question 4

combination of all forces that act on an object

Answer 4

net force

Question 5

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

Answer 5

gravity

Question 6

amount of matter an object has measured in kilos

Answer 6

mass

Question 7

measure of force of gravity on an object how hard they pull center of earth

Answer 7

weight

Question 8

the net force acting on an object causes the object to accelerate in relation to the size of the force and the mass of the object F= MA force= mass x acceleration

Answer 8

newtons second law

Question 9

is a that opposes motion between two surfaces that are touching each other

Answer 9

friction

Question 10

resists getting an moving

Answer 10

static friction

Question 11

sliding rolling resists keeping an object moving (happens when its moving)

Answer 11

kinetic friction

Question 12

to every action there is an equal and opposite reaction force

Answer 12

newtons 3rd law

Question 13

anything that is thrown or shot through the air

Answer 13

projectile

Question 14

force acting the center of a curved or circular path

Answer 14

centripetal force

Question 15

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

Answer 15

momentum
