Kinematics
This is the acceleration at the very top point on the path of a projectile.
9.8 m/s2
This is the force of a surface pushing back on an object acted on by gravity.
Normal force
This is the rotational version of mass.
moment of inertia
Since momentum has both magnitude and direction it can be classified as this.
vector
This American poet's most well known works include "Mending Wall", "Fire and Ice", and "Stopping by Woods on a Snowy Evening"
Robert Frost
This is the velocity at the very top point on the path of a projectile.
0 m/s
This is the type of picture that can (should) be drawn for any dynamics problem.
free-body diagram
I = mR2+...
This is the name we give for the change in momentum.
impulse
This scientist's work on the physics of motion, Principia, is the foundation for physics classes. He is also credited with inventing Calculus.
Isaac Newton
This is the value that can be found from the slope of a position vs. time graph.
velocity
This is the direction that kinetic friction acts on an object.
opposite of the motion
This is what we use to find the direction of rotational velocity, rotational acceleration, and rotational momentum.
right hand rule
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.
11.3 m/s
This person is the one referred to by "Tippecanoe" in the campaign song "Tippecanoe and Tyler Too" for the Whig Party's 1840 campaign.
William Henry Harrison
These quantities stay constant during both horizontal and angled projectile problems.
g, vx
This is the direction of the tension in a string when you twirl a ball in a circle above your head.
toward the center
These are the conditions for rotational static equilibrium.
net torque = 0 Nm
Fnet, y = 0 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.
0
(momentum is conserved)
This duo's works include "The Sound of Music", "South Pacific", and "Oklahoma!" just to name a few.
Rodger's and Hammerstein
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.
1.60 seconds
This is the normal force on a 10 kg object that rests on an incline that makes a 25 degree angle with the horizontal.
90.6 N
An object travels in a circular path of radius r at a constant speed v. if the radius of the circle is doubled and the speed stays unchanged, this is what happens to the object’s acceleration.
ar is half of its previous value
This is the symbol used to represent angular momentum.
