Kinematics
This is the acceleration at the very top point on the path of a projectile.
9.8 m/s2
This is the force of a surface pushing back on an object acted on by gravity.
Normal force
This is the rotational version of mass.
moment of inertia
Since momentum has both magnitude and direction it can be classified as this.
vector
This Greek mathematician is often referred to as the "father of geometry," which includes establishing axioms and proving many theorems
Who is Euclid?
This is the velocity at the very top point on the path of a projectile.
0 m/s
This is the type of picture that can (should) be drawn for any dynamics problem.
free-body diagram
I = mR2+...
This is the name we give for the change in momentum.
impulse
This letter, which is first in the Greek alphabet, can be used to represent angular acceleration. It can also be used to refer to a person who is the leader of a pack.
What is alpha?
This is the value that can be found from the slope of a position vs. time graph.
velocity
This is the direction that kinetic friction acts on an object.
opposite of the motion
When calculating the effect of the mass distribution in AP Physics 1, we use a chart to find this number, which completes the equation inertia equation
What is the coefficient?
This is the final velocity a 500 kg car that starts at rest will have after it is rear-ended by a 650 kg that is initially going 20 m/s. The cars lock together after they hit.
11.3 m/s
This letter, which is the 18th in the Greek alphabet, can be used to mean the "sum of," or to insult a member of Gen Z
What is Sigma?
These quantities stay constant during both horizontal and angled projectile problems.
g, vx
This is the direction of the tension in a string when you twirl a ball in a circle above your head.
toward the center
These are the conditions for rotational static equilibrium.
net torque = 0 Nm
Fnet, y = 0 N
A 5 kg loaded rifle is initially held at rest and then fired. The 0.05 kg bullet leaves the barrel at 450 m/s. This is the final momentum of the bullet-gun system.
0
(momentum is conserved)
This letter, which the ninth letter in the Greek alphabet, resembles a lower case i, but stands for an imaginary number, NOT inertia.
What is Iota?
This is how long it will take a 5 kg object to hit the ground if dropped from rest at a height of 12.5 m. You can ignore air resistance.
1.60 seconds
This is the normal force on a 10 kg object that rests on an incline that makes a 25 degree angle with the horizontal.
90.6 N
An object travels in a circular path of radius r at a constant speed v. if the radius of the circle is doubled and the speed stays unchanged, this is what happens to the object’s acceleration.
ar is half of its previous value
This is the symbol used to represent angular momentum.
L
Name the two Greek letters which may be confused with each other due to the sound of one resembling the appearance of the other.
What are Pi and Rho or Omega and Upsilon?
