1. Formula
2. Substitution
3. Answer

# data[].attributes.body
W = Fs
W - Work (J)
F - Force (N)
s - distance (m)

# data[].attributes.body
Ek = 0.5mv²
Ek - Kinetic energy (J)
m - mass (kg)
v - velocity (m/s)

# data[].attributes.body
Eg = mgh
Eg - Gravitational potential energy (J)
m - mass (kg)
g - gravity (9.8)
h - height (m)

# data[].attributes.body
Fw = mg
Fw - Weight (N)
m - Mass (kg)
g - gravity (9.8 m/s²)

# data[].attributes.body
Identify if an object is moving/not moving (stationary won't have sideways forces, moving will have double forces on the sides)
Identify the motion of the object
(equal forces, constant motion or stationary, unequal forces accelerating)

# data[].attributes.body
F = ma
F - Force (N)
m - Mass (kg)
a - acceleration (m/s²)

# data[].attributes.body
1st - Objects will stay in constant motion or stationary unless acted on by a unbalanced external force
2nd - Acceleration is proportional to the force applied to the object and inversely proportional to the mass of the object
3rd - For every action there is an equal and opposite reaction

# data[].attributes.body
m/s --> km/h  - x3.6
km/h --> m/s - /3.6

# data[].attributes.body
a = (v - u)/t
v = u + at
a - acceleration (m/s²)
v - final velocity (m/s)
u - initial velocity (m/s)
t - time

# data[].attributes.body
v = s/t
t = s/v
s = vt
v - velocity/speed (m/s)
t - time (s)
s - distance/displacement (m)

# data[].attributes.body
Speed = position on y-axis
Crosses x axis = stationary/stops
Gradient = acceleration/deceleration
Flat line = constant speed
Area under the curve = displacement of object

# data[].attributes.body
Horizontal line = stationary
Gradient = speed (steeper = faster)
Total distance covered = total up + total down
Total displacement = difference between start and finish
Curves or changes in gradient = acceleration

# data[].attributes.body
Show the motion of an object

# data[].attributes.body
Direction and Quantity
Examples: Velocity, Displacement, Force, Acceleration

# data[].attributes.body
No direction, just quantity
Examples: Distance, Speed, Mass
