Kevin the Cube
A sheet of paper and a car are dropped at the same time. With no air resistance, which one hits the ground first AND why?
They hit the ground at the same time because they have the same acceleration due to gravity
What are the 2 things the acceleration of an object depends on?
Net force acting on an object
Mass of the object

Time
In physics, what are the units for acceleration?
m/s2

What do each of these forces represent?
Fa, Fg, FN, FT, FF
Fa = force applied
Fg = force of gravity (weight)
FN = normal force
FT = tension force
FF = force of friction
True or false: momentum is conserved in all events (collisions, explosions, etc.)
True! Conservation of momentum
What are the units for force?
Newtons or N

Mater’s license plate is a subtle Easter egg treasured by Pixar fans and animators. What is Mater’s license plate number, and why is it significant in Pixar’s legacy?
Mater’s license plate reads “A113,” referencing the classroom number at the California Institute of the Arts (CalArts) where many Pixar animators got their start. “A113” appears as a hidden reference in numerous Pixar films, honoring the roots and shared history of its creators.
(This is actually a forces question)
If a 2 kg object has an acceleration of 15 m/s2, then what is the force associated (don't forget the units!)?
30 N!
True of false: the force of gravity and weight are the same force.
True
If object A is the same mass as object B, but object B has more momentum than object A, then what must object B have?
More velocity/speed (than object A)!
What is the "system" of units in physics and science called?
SI, or Système international
