Q

Uniform Motion (uninterrupted)

A

An object traveling at a constant rate in a straight line

-Great for calculation but in real life it is impossible to maintain for long periods of time.

16
Q

Higher Velocity, Lower Velocity and No change in Velocity

A

HV- Acceleration
LV- Deceleration
NCIV- steady speed the whole time

17
Q

Figuring Out Average Speed

A

Distance traveled/ Time elapsed
OR
d final-d Initial/ t final - d initial

18
Q

Km/h –> m/s

A

divide by 3.6

19
Q

m/s –> km/h

A

multiply by 3.6

20
Q

Speed

A

The rate at which something or someone is able to move or operate at

21
Q

Velocity Definition

A

The speed of something in a given direction (E)

-Change of displacement during a specific time

22
Q

Distance

A

The amount of space between two things

23
Q

Displacement

A

The movement of something from its original position. The amount travelled since the initial position.

24
Q

Scalar Quantity

A

measures the magnitude of something

EX- Speed

25
Q

Vector Quantity

A

Measurement that refers to the magnitude and the direction something has travelled. EX-Velocity

26
Q

Arrow on top of variable

A

the arrow indicates the referral of a vector quantity

27
Q

Acceleration

A

A change in velocity during a specific time
-Is a vector quantity (has direction and amount)
Acceleration will be squared in equations

28
Q

Positive Acceleration

A

-Both the change in magnitude of velocity and the direction are positive or negative

Speeds up in right direction (right)
Slows down in Wrong direction (left)

29
Q

Negative Acceleration

A

-The change in Magnitude of velocity is negative while the direction is positive or the other way around.

EX- Gravity

slow down in right direction (right)
speed up in wrong direction (left)

30
Q

Formula for Acceleration

A

A= change in v/change in t

31
Q

Why cant acceleration be a negative number

A

because you cannot go back in time (realistically)

32
Q

Newtons 3 Laws

A
  1. Every object will remain at rest or in uniform motion in a straight line unless compelled to change its state by an action of external force
  2. The velocity of an object changes when its subjected to an external force (FORCE MEASURED IN NEWTONS)
  3. For every action/force in nature there is an equal and opposite reaction.
33
Q

Force

A

force = mass X acceleration. It is a vector quantity so its acts in a direction.

since a= v/t…..f=m X v/t

34
Q

Work

A

Work is expressed in the units of Joules. Work measure how far you have travelled from your initial position.
W= f X d

W also equals the change in energy

35
Q

How many KJ are in a J

A

1000

36
Q

Gravitational Potential Energy

A

The energy that is stored caused by being in a resting position.
m X h X g

37
Q

Kinetic energy

A

potential energy converts into kinetic energy once in motion and the energy is no longer stored.
EK = 1/2mv2

38
Q

Gravity on earth

A

9.81m/s2

39
Q

gravity on earth compared to gravity on the moon and Jupiter

A

the moons gravity is slower around 1.6m/s2 and the gravity on Jupiter is higher around 24.8m/s2.
