Motion
What is the instantaneous velocity?
A large, heavy object is being pushed to the right with a 100 N force across a rough floor with a constant velocity. This quantity equals 0.
What is the net force?
The distance an object travels when completing a full circle.
What is circumference?
What is parallel to the object's motion?
The trick to winning an egg drop contest
What is increasing t in order to decrease F?
The magnitude of this quantity equals 0 when an object traverses one full circle in a given amount of time.
What is the average velocity?
Terminal velocity occurs when this quantity equals 0 on a falling object.
What is the net force?
The mass in the formula v = (GMr)1/2 is the mass of which object
What is the mass of the object being orbited?
The location in the motion where the kinetic energy of a pendulum is greatest.
What is at the bottom of the motion?
The type of collision that conserves both energy and momentum.
What is an elastic collision?
This equation sometimes leads to the quadratic formula.
x = xo + vo t+ 1/2 a t2
A table cloth being yanked out from under a set of dishes without the dishes falling is a demonstration of which law?
What is Newton's 1st Law?
An object is moving in a circle at constant speed. The object's acceleration points
What is inward, toward the center of the circle?
What is when the spring is neither stretched nor compressed?
What is momentum is conserved in both directions?
This equals 0 at the top of a projectile's motion.
What is its vertical velocity?
A bug impacts a windshield. The 3rd law force pair to this is?
What is the windshield impacting the bug?
When the distance between two massive objects doubles, the force between them
What is decreases by a factor of 4?
This quantity changes when an object changes height
What is gravitational potential energy?
The reason two objects with the same mass and speed can have different momenta
What is momentum is a vector?
An object is moving to the right with a decreasing velocity, resulting in this quantity pointing to the left.
What is acceleration?
A block is pulled up an incline with an increasing velocity. This points down the incline.
What is the force of friction?
What is partly tangent to the circle in the direction of motion and partly toward the center of the circle?
The amount of work done by a normal force as a block slides across a horizontal floor
What is 0?
Why the momentum of only one object is not conserved when two objects collide
What is the system is not closed?
