Kinematics
This is the acceleration at the very top point on the path of a projectile
What is 9.8 m/s/s ?
This is the object that feels the Newton's 3rd law of your weight.
What is the Earth?
This is the name we give for the change in momentum.
What is impulse?
This is the rotational version of mass
What is moment of inertia?
These are the two fundamental types of electric charges.
What are positive and negative?
This is the distance that a ball released from rest will fall during the 2nd second if it traveled distance H during the first second.
What is 3H?
This is the type of diagram that can (should) be drawn for any forces problem.
What is a free-body diagram?
This type of energy is used when an object is not kept at the same elevation. Formula: Ug = mgh
What is gravitational potential energy?
When THIS equation is true we know that an object is rolling without slipping.
What is v = r * omega?
This is the saying that dictates electric attraction and repulsion.
What is "opposites attract (and likes repel)"?
This is the value that can be found from the area under the curve of a velocity-time graph.
What is displacement?
This is the direction that kinetic friction acts on an object.
What is the opposite of the motion?
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.
What is 11.3 m/s?
This is how we describe an object moving in a circle of constant radius at constant speed.
What is Uniform Circular Motion?
F = k q1 q2 / r^2
What is Coulomb's Law
This is the type of acceleration that an object must have in order to use the kinematic equations to solve.
What is constant acceleration?
This is the direction of the tension in a string when you twirl a ball in a circle above your head.
What is toward the center?
A spring is stretched 2m from equilibrium and 4J energy was used. This is the spring constant.
What is k = 2 N/m?
This is the symbol used to represent angular momentum.
What is the letter "L"?
1.6 x 10^-19 C
What is the elementary/electron charge
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.
What is 1.60 seconds?
This is the magnitude of the normal force on a 10 kg object that rests on an incline that makes a 25 degree angle with the horizontal.
What is 90.6 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.
What is zero?
If a box, ball, and thin hoop with the same size and mass are released down a frictionless ramp, THIS is the object that will reach the bottom first.
What is a three-way tie?
This is what allows non-touching electric charges to interact.
What is the Electric Field?
