Forces

Question 1

Force

Answer 1

A push or pull one body exerts on another

Question 2

Newton’s 1st Law of Motion

Answer 2

An object moving at that velocity, an object at rest stays at rest. UNLESS ACTED OPON BY A NET FORCE

Question 3

Intertia

Answer 3

The tendancy 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 object exerts a force on every other object. This force is Gravity felt as a pull

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 object’s mass; how hard an object is pulled toward center of earth.

Question 8

Newton’s 2nd Law of Motion

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

A force that opposes motion between two surfaces that are touching each other.

Question 10

Static Friction

Answer 10

Friction that resists getting an object moving ( this is when objects aren’t moving)

Question 11

Kinetic Friction

Answer 11

Sliding friction, Rolling friction, resists keeping an object moving (happens while it’s moving)

Question 12

Newton’s 3rd Law of Motion

Answer 12

“To every action there is an equal (in size) and opposite (in direction) reaction force”.

Question 13

Projectile

Answer 13

Anything that’s thrown or shot through 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! The force required to stop a moving object.
