Kinematics
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 Newton's 3rd law pair for the weight of an object on Earth.
What is the force the object pulling on the Earth?
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 distance that a ball released from rest will fall during the 2nd second if it traveled distance H during the first second.
What is 3H?
This is the type of picture that can (should) be drawn for any dynamics problem.
What is a free-body diagram?
When THIS equation is true we know that an object is rolling without slipping.
What is v = r(omega)
This is the name we give for the change in momentum.
What is impulse?
This is the value that can be found from the area under a velocity-time graph.
What is displacement?
This is the direction that kinetic friction acts on an object.
What is opposite of the motion?
This is what we use to find the direction of rotational velocity, rotational acceleration, and rotational momentum.
What is the 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.
What is 11.3 m/s?
This is the type of acceleration that an object must have in order to be able to use the top three equations on your equation sheet.
What is constant?
This is the direction of the tension in a string when you twirl a ball in a circle above your head.
What is toward the center?
This is what must be true for an object to be in rotational equilibrium.
What is 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 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.
What is 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.
What is 90.6 N?
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 symbol used to represent angular momentum.
What is L?
