Measurements & Numbers
How many zeros does googol have
100 zeros
What is acceleration
The change in velocity divided by the change in time
difference between distance and displacement
distance is the complete length, displacement is the length between two points.
What is force
An action that can change motion, Push, and pull.
what is friction
a force that opposes motion between two forces
What are the design thinking steps
empathize, define, ideate, prototype and test.
how is acceleration shown on a graph
a curved line
what does Vnot stand for
initial starting value
Whats Inertia
The ability of an object to resist a change in its state of motion
what does the force of gravity equal
9.8
what is the scientifitc notation for milli
10-3
What is slope on a V-t graph
A (acceleration)
how do you calculate average speed
total distance over the total time of travel
Whats newtons first law
An object at rest stays in rest and a object in motion stays in motion.
formula of hooke's law
F=-kx
what is the scientific notation for giga
109
What does a horizontal line on a velocity graph indicate
object is at rest (no movement)
what are vectors
quantities with both magnititude and direction
Whats the equation to find mass
F/A = M
--->35 + <--- 15 = ?
3 fundamental units in physics?
meter, second, kilogram
what is the formula for acceleration
acceleration= final velocity - initial velocity/ change in time with a direction
a car is moving 8m/s, how much acceleration is needed for it to stop at 3s
A= - 2.67
Newtons 3 law
For ever action force there has to be a reating force that is equal in strength and opposite in direction
an upward force exerted by a fluid that opposes the weight of an immersed object is called..
