New cards
2

Equation of velocity

V=d/t

New cards
3

Velocity

Speed in a given direction

New cards
4

Newton’ first law of motion

An object in motion will stay in motion at the same speed and direction unless acted upon by an unbalanced force

New cards
5

Equation of acceleration

A=v/t

New cards
6

Acceleration

When an object changes speed or changes direction

New cards
7

Rolling friction

The force resisting the motion of a rolling body on a surface

New cards
8

Sliding friction

The resistance created by any two objects when sliding against each other

New cards
9

Fluid friction

When fluids are moving relative to each other

New cards
10

What are the 3 types of friction?

Fluid friction, rolling friction, and sliding friction

New cards
11

Spring force

The force required to extend or compress a spring, the spring will push or pull against whatever you are doing it to

New cards
12

Potential energy

The energy possessed by an object of its relation to another object

New cards
13

Static

Original form of an object with no energy

New cards
14

Buoyant force

The upward force that’s on an object completely or partly in a fluid

New cards
15

Archimedes principle

A result when an object is totally or partially immersed in a fluid is subject to an upward force equal in magnitude to the weight of the fluid

New cards
16

Friction

The resistance that one surface or object encounter when moving over another

New cards
17

Lift force

The force that opposes the weight of an object and causes it to rise into the air

New cards
18

Gravity

The force that attracts a body towards the center of the earth or any other form of mass

New cards
19

Acceleration of gravity

9.8m/s/s

New cards
20

Applied force

Force which is applied to an object by another object

New cards
21

Newton

The main label of force

New cards
22

Viscosity

Thickness of a fluid

New cards
23

Newton’s third law of motion

For every action (force), there is an equal and opposite reaction (force)

New cards
24

Air resistance

The force exerted by the air on things moving through it
