Kinematics & Dynamics
The slope of a Velocity vs Time graph represents this physical quantity
What is Acceleration
This theorem states that the net work done on an object is equal to its change in kinetic energy
What is the Work Energy Theorem
This center seeking force is required to keep an object moving in a circle
What is Centripetal Force
This rotational equivalent of mass depends on how an object's mass is distributed relative to the axis of rotation
What is Rotational Inertia or Moment of Inertia
This is the time it takes for a system to complete one full cycle of motion
What is Period
This law states that the acceleration of an object is directly proportional to the net force acting on it and inversely proportional to its mass
what is Newton’s Second Law
This is the type of collision where both total momentum and total kinetic energy are conserved
what is Elastic Collision
According to Newton's Law of Universal Gravitation if the distance between two planets doubles, the gravitational force changes by this factor
What is 1/4 or decreases by 4
An ice skater pulls her arms in to spin faster so she is decreasing her rotational inertia to conserve this quantity
What is Angular Momentum
This is the number of cycles an oscillator completes per second
What is frequency
If an object is moving at a constant velocity, the net force acting on it must be this value
what is zero
This quantity defined as the product of force and time is equal to the change in an object's momentum
what is impulse
This is the term for the acceleration of an object moving in a circle at a constant speed (which points toward the center)
What is Centripetal acceleration
If a disk and a hoop of the same mass and radius race down an incline, this one wins
What is The disk
The maximum displacement of an oscillator from its equilibrium position is called this
What is amplitude
A ball is thrown horizontally off a cliff. This is the only force acting on the ball (air resistance is negotiable) while it is in the air
what is Gravity
If the speed of a car triples its kinetic energy increases by this factor
What is 9 times
For a car rounding a flat curve, this specific force provides the centripetal acceleration
What is Static Friction
An object is balancing if the net torque acting on it is equal to this
What is zero
At the equilibrium position of an oscillating pendulum, this form of energy is at its maximum
What is Kinetic Energy
To calculate the coefficient of static friction, you divide the maximum frictional force by this (perpendicular) force
What is Force Normal or Normal Force
In a perfectly inelastic collision this physical quantity is definitively not conserved (as the objects stick together)
What is Kinetic Energy
If the mass of a planet is doubled but its radius stays the same, the surface gravity (g) changes by this factor
What is it doubles
For an object rolling without slipping, its total kinetic energy is the sum of these two types of energy
What is Transnational and Rotational Kinetic Energy
The period of a mass spring system depends on the mass and this property of the spring
What is spring constant or k
