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 force 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/velocity depends on.
What are the frequency and wavelength?
This is how a large object and a small object must be arranged to balance a seesaw (i.e. which of the two should be closer or farther from the center/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 relationship between the frequency and the period.
What is an inversely proportional relationship or a reciprocal?
This is what must be true for an object to be in rotational equilibrium.
When does the torque on either side must be equal?
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 type of collision that happens.
What is elastic collision?
This is the reason why the total energy throughout the path of a rollercoaster remains the same.
What is the law of conservation of energy?
This is how you find the acceleration when given a velocity vs. time graph.
What is the slope of the velocity vs. time graph?
This is the effect (increase or decrease - select one) on wavelength when the frequency is increased.
What is a decrease (or shorter) on wavelength?
This is the factor that a number in units of revolutions must be MULTIPLIED to if we wanted to convert it to radians.
What is 1/(2pi)?
These are the units used to represent impulse.
What is kg m/s OR Ns?
This is the final speed of an object which drops from 5 m. (Hint: use the law of conservation of energy and g = 10 m/s2).
What is 10 meters per second?
