The 5 steps of design thinking
Empathize, Define, Ideate, Prototype, Test
1D Motion is....
Movement along a straight line
Length of the path traveled
distance
an action that can change motion
Force
How do you find friction?
ffrict = µN
An easy way to write very large & small numbers
Scientific Notation
Speed with direction
Velocity
difference between displacement and distance
displacement is the shortest distance of two point while distance is the length of the path
Newton's 1st Law is..
An object at rest stays at rest and an object in motion, stays in motion with the same speed and in the same direction unless acted upon by an unbalanced force.
An upward force exerted by a fluid that opposes weight of an immersed object.
Buoyancy
Interpolation
_______ is shown as a curved line in a D-T graph
Acceleration
scalars and vectors are....
scalars: quantities that are fully described by a magnitude alone
vectors: quantities that are fully described by both a magnitude and a direction
How do you find acceleration?
a= f/m
The difference between Static and Kinetic friction
Static: Object is not moving
Kinetic: Object is moving
The symbol of micro-
µ
Not moving for a certain amount of time
Stationary
If a Creature Cat’s Ferrari, with an initial speed of 10 m/s, accelerates at a rate of 50 m/s/ for 3 seconds, what will its final speed be?
160 m/s
An African elephant can reach heights of 13 feet and possess a mass of as much as 6000 kg. Determine the weight of an African elephant in Newtons and in pounds. (Given: 1.00 N = .225 pounds)
58800 N or 13230 lb

A Cessna 150 airplane has a takeoff speed of 27.9 m/s (62.5 mi/hr). Determine the minimum length (in m) of the runway which would be required for the plane to take off if it averages an acceleration of 1.81 m/s/s.
215 m
The Top Thrill Dragster stratacoaster at Cedar Point Amusement Park in Ohio uses a hydraulic launching system to accelerate riders from 0 to 54 m/s (120 mi/hr) in 3.8 seconds before climbing a completely vertical 420-foot hill . Determine the net force required to accelerate an 86-kg man.

A hockey puck has a coefficient of kinetic friction of μk = .10. If the puck feels a normal force (FN) of 5 N, what is the frictional force that acts on the puck?
0.5N
