Kinematics and Dynamics
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 distance between consecutive wave crests
What is the wavelength?
This is the rotational version of mass.
What is moment of inertia?
Since momentum has both magnitude and direction it can be classified as this.
What is a vector?
This is the sum of potential and kinetic energy
What is mechanical energy?
This is the type of picture that can (should) be drawn for any dynamics problem.
What is a free-body diagram?
This is the amount of cycles per unit time
What is frequency?
This is the rotational version of force
What is torque?
This is the name we give for the change in momentum.
What is impulse?
This is the change in energy
What is work?
This is the value that can be found from the area under a velocity-time graph.
What is displacement?
These are what wave speed depends on
What are the properties of the medium only?
This is how a large object and a small object must be arranged to balance a seesaw
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?
These are the two main types of potential energy
What are spring/elastic and gravitational energy?
This is the direction of the tension in a string when you twirl a ball in a circle above your head.
What is towards the center?
This is when only one anti-node (point of maximum displacement) occurs in a standing wave on a string
What is the fundamental frequency?
This is what must be true for an object to be in rotational equilibrium.
When does the net torque equals zero?
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?
This is the type of collision when energy is conserved
What is an elastic collision?
This is how you find the sign of acceleration from a position vs. time graph
What is the concavity?
This is the the condition that must be met to allows standing waves to form
What is the length of the string equals multiples of the wavelength divided by two?
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 the final speed of an object which drops from 5 m.
What is 10 meters per second squared?
