1D Kinematics
Distance and speed are two examples
What are scalars?
a2+b2=c2
What is Pythagorean Theorem?
The constant downward acceleration acting on projectiles near Earth’s surface.
What is gravity?
An object at rest will remain
at rest, and an object in motion will remain in motion.
What is Newton's First Law?
mgh
What is Gravitational Potential Energy?
How fast you go vs how fast you get fast
What is velocity vs acceleration?
Opposite side / adjacent side
What is the tangent of the angle?
For maximum range, a projectile should be launched at this angle.
What is 45 degrees?
The only thing that can cause an object to accelerate.
What is a force?
Joules
What is the unit for energy?
The velocity of a ball thrown in the air right before it falls back down.
What is 0m/s?
Motion appears differently depending on your frame of reference.
What is relativity?
The component of velocity that remains constant throughout projectile motion.
What is horizontal velocity?
The force exerted by a rope, chain, or string.
What is tension?
Energy cannot be created or destroyed.
What is the conservation of energy?
A flat slope on a velocity vs time graph.
What is zero acceleration?
Placing the tail of the second vector on the tip of the first vector.
What is vector addition?
This term describes the curved path followed by a projectile under constant gravity
What is a parabola?
***Daily Double***
For every action there is an equal and opposite reaction.
The rate at which work is done.
What is power?
v0t +1/2at2
What is the change in position (delta y: yf-y0)?
The single vector sum of two or more vectors added together, representing the overall effect (magnitude and direction) of multiple vectors acting on an object.
What is a resultant vector?
This initial quantity is broken into horizontal and vertical components using sine and cosine.
What is initial velocity?
The force that prevents the motion of a stationary object.
What is static friction?
The ability to transfer energy
What is work?
