forces

Question 1

Force

Answer 1

A push or a pull one body exerts on another

Question 2

Newtons 1st Law

Answer 2

An object moving, keeps moving at that velocity, object at rest stays at rest unless acted upon by a net force

Question 3

Inertia

Answer 3

The tendency of an object to resist any change in motion

Question 4

Net Force

Answer 4

combination of all forces that act on an object

Question 5

Gravity

Answer 5

Every single object exerts a force on every other object

Question 6

Mass

Answer 6

the amount of matter or “stuff” an object has, Measured in kilograms

Question 7

Weight

Answer 7

Measure of force of gravity on an objects mass, how hard the object is pulled toward the center of the earth

Question 8

Newton’s 2nd Law

Answer 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

Question 9

Friction

Answer 9

opposes motion between two surfaces that touch each other

Question 10

Static friction

Answer 10

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

Question 11

kinetic friction

Answer 11

resists keeping an object from moving (while its moving)

Question 12

Newtons 3rd law

Answer 12

to every action there is an equal (in size) and opposite (in direction) reaction force

Question 13

Projectile

Answer 13

anything thrown or shot in the air

Question 14

centripetal force

Answer 14

force acting toward the center of a curved or circular path

Question 15

momentum

Answer 15

mass on the move
