Measurements & Numbers
measurements & numbers
What are the basic concepts to start learning about physics?
speeding up or slowing down
Speed (v)
What is "rate at which distance changes"?
Motion under forces
What is dynamics?
every action force there has to be a reaction force that is equal in strength and opp. in direction.
power's of 10
What is scientific notation?
covering the same distance over the same amount of time
what is constant speed
Velocity
What is "rate at which displacement changes"?
an action that can change motion, a push or pull
What is force?
the amount of matter in an object. the force of gravity on the objects matter
what is mass vs weight
The origin of the modern # system
Why is India important in physics?
speed with direction
what is velocity
Vectors
What is "quantities with both magnitude and direction"?
term used to measure the ability of an object to resist a change in its state of motion
a force that opposes motion between two surfaces
what is friction
empathize, define, ideate, prototype, test
What are the steps for design thinking?
speed is increasing at a constant rate
what is V.T graph
Average Speed
What is "calculated from total distance over total time of travel"?
The acceleration of an object directly proportional to the magnitude of the net force, in the same direction of the net force, and inversely proportional to the mass of the object.
What is Newton's 2nd Law?
object is not moving
what is static friction
common measurements/units in physics
What are meter (m), second (s), & kilogram (kg)?
acceleration is shown as a curved line.
what is D.T graph
A car drives at 22 miles and accelerates at 1.6m/s/s in 6.8 seconds. Find V.
What is "2.9m/s"?
describes the "ideal" spring, an approximation for real springs; f = -kx
What is Hooke's Law?
what is kinetic friction
