This force is perpendicular to the surface and goes through the center of the mass of the object.
What is normal force?
This is the number of radians traveled in one complete revolution around an axis
What is 2pi ?
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 a zero?
This American poet's most well known works include "Mending Wall", "Fire and Ice", and "Stopping by Woods on a Snowy Evening"
Who was Robert Frost?
This equation is used to determine linear velocity for an object that is rolling without slipping.
What is velocity = radius x angular velocity
This is change in momentum and also equal to a product of
What is force and time?
This is two times GM divided by velocity of light squared
What is Schwarzschild radius of a black hole?
For a projectile in 2D motion, acceleration is zero here.
What is horizontal?
What is greater?
What is torque times delta t?
What is angular impulse?
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 created when a star with a core mass of 3 or solar masses or more dies
What is a stellar black hole?
When the car starts with the twice the initial velocity, it stops at this times the original distance.
What is horizontal? What is four times?
This is what must be true for an object to be in rotational equilibrium.
What is net torque equals zero?
In this reference frame, the velocities of the two incoming particles for a collision are in opposite directions.
What is center of mass frame
When a planet revolves around a star, it changes the star to do this when it moves the star's orbit center.
What is the wobble?
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?
Momentum of a system is conserved as long as
What are no external forces exerted on the system?
This formula describes the relationship between energy, mass, and the speed of light.
What is E = mc2 ?
