The spring force is F = -kx because spring force is a ______ force.
______ is a vector, and speed is a scalar.
What is velocity?
These two components act inwards (towards the center) of the circle created by the circular motion of an object.
What is centripetal force and centripetal acceleration?
This type of collision conserves momentum of the system, but does not conserve the kinetic energy of the system.
Torque is defined by this type of vector multiplication operation.
What is a cross product?
An object in simple harmonic motion has the highest velocity at the instant it passes through its ___________ position.
What is equilibrium
This law states that F=ma.
What is Newton's Second Law?
This Newtonian equation follows the Inverse Square Law.
What is Newton's Law of Universal Gravitation?
True or False: In a closed system, a change in potential energy must mean an equal and opposite change in kinetic energy.
True
The change in potential energy of a system with respect to distance
What is Force?
True or False: Spring force is proportional to the square of the displacement of the spring.
False
True or False: an object instantaneously at rest must mean that its acceleration is zero.
False
When spinning a ball attached to a string in a horizontal circle, the tension force of the string provides this type of force.
What is centripetal force?
True or False: Applying a force F on an object for a distance d parallel to the surface that the object is traveling on will result in the same amount of work done, regardless of whether or not the surface is inclined.
True
A certain one-dimensional conservative force is given as a function of x by the expression F = -kx3, where F is in Newtons and x is in meters. Solving for this particular measurement results in the equation -¼kx4.
What is Potential Energy?
This is the equation for the position of an object in harmonic motion as a function of time.
cos(ωt + φ)
This is the value given when finding the slope of a velocity-time graph.
What is acceleration?
This is the component that always equals zero when applying a force parallel to a rotating object's radius, no matter how much force is applied
What is torque?
This measurement is provided by the area bounded by the curve and the x-axis of a force-time graph
What is Momentum?
This object's rotational inertia around its central diameter axis of rotation is ¼MR2 + ¹⁄₁₂ML2.
What is a solid cylinder?
A pendulum system has a kinetic energy K and potential energy U = 0 when it is at its lowest point in its oscillatory motion. This is the angle that the pendulum makes with the horizontal at the instant the system's kinetic energy and potential energy are equal.
What is 30 degrees?
Block 1 and block 2, both of identical masses are resting on top of each other, with block 2 on top of block 1. This block has a greater normal force than the other.
The normal force exerted on a person varies at every instant in this type of circular motion.
What is vertical circular motion?
This theorem states that work is defined as the change in kinetic energy.
What is the Work-Energy Theorem?
The net work done when an object travels through this type of conservative field is zero when the object is thrown upwards and lands at the same position it was thrown from.
What is the Force of Gravity?
