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 position.
What is angle?
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 total 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 distance/displacement?
These are what wave speed depends on.
What are frequency and wavelength?
This is how a large object and a small object must be arranged to balance a seesaw (aka which of the two should be closer to the fulcrum)?
What is the larger object closer to the center and the smaller object farther from the center?
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 the type of relationship between period and frequency.
What is inversely proportional / reciprocal?
This is what must be true for an object to be in rotational equilibrium.
The torque on each side must be equal.
A 5 kg loaded rifle is initially held at rest and then fired. The 0.05 kg bullet, that was inside the barrel, 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 the part of the velocity vs. time graph that you look at to find the acceleration.
What is the slope?
These are waves that move parallel to the direction of wave motion.
What are longitudinal waves?
If two ladybugs were on the same line in a revolving disk, but ladybug A is farther from the center than ladybug B, which of the two will have a greater angular velocity?
Both will have equal angular velocity (both cover the same angle per unit time)
This is the unit used to represent momentum.
What is p?
This is the final speed of an object which drops from 5 m.
What is 10 meters per second squared?
