Force vocab

Question 1

Formula used to calculate force

Answer 1

Force= mass•acceleration

Question 2

Contact force

Answer 2

When 1 object pushes or pulls on another by touching it

Question 3

Gravity

Answer 3

The force of attraction between two objects

Question 4

Friction

Answer 4

A force that resists motion between two surfaces that pressed together

Question 5

Magnetic force

Answer 5

Force exerted between electrically charged moving particles to create a field

Question 6

Net force

Answer 6

Overall force on an object when all forces are acting on it combined

Question 7

Balanced force

Answer 7

When two opposite forces are EQUAL then the net force

= 0 newtons

Question 8

Unbalanced force

Answer 8

When two forces act in the same direction they ADD, and when two forces act unequally inthe opppsite direction they SUBTRACT.

Question 9

Force

Answer 9

push or pull that causes an object to start moving, stop moving, or change directions.
(vector quantity)

Question 10

Inertia

Answer 10

The resistance of an object to change

The greater an objects mass, the greater its inertia

Question 11

First law of motion

Answer 11

Objects at rest stay at rest, and objects in motion stay in motion unless acted on by an unbalanced force.

Question 12

Newton’s 2nd law of motion

Answer 12

Force=mass•acceleration

Question 13

Newton’s 3rd law of motion

Answer 13

For every action, there is an equal and opposite reaction
