- What is the definition of displacement?
Show answer
The change in position; a vector quantity- What is the difference between distance and displacement?
Show answer
Distance is total path length traveled (scalar); displacement is change in position (vector)- State the kinematic equation for velocity when time is unknown.
Show answer
v^2 = v0^2 + 2a(x - x0)- What is instantaneous velocity?
Show answer
The derivative of position with respect to time; velocity at a specific instant- What is average acceleration?
Show answer
Change in velocity divided by change in time- State Newton's first law.
Show answer
An object at rest stays at rest, and an object in motion stays in motion unless acted upon by a net force- State Newton's second law.
Show answer
The net force on an object equals its mass times its acceleration (F = ma)- State Newton's third law.
Show answer
If object A exerts a force on object B, then object B exerts an equal and opposite force on object A- What is the SI unit of force?
Show answer
Newton (N), equivalent to kg·m/s^2- What is inertia?
Show answer
The tendency of an object to resist changes in its motion; directly related to mass- How is work defined in physics?
Show answer
Force applied in the direction of motion times the displacement (W = F·d·cos(theta))- What is kinetic energy?
Show answer
The energy of motion; KE = (1/2)mv^2- What is gravitational potential energy near Earth's surface?
Show answer
PE = mgh, where m is mass, g is gravitational acceleration, and h is height- State the work-energy theorem.
Show answer
The net work done on an object equals its change in kinetic energy- What is power?
Show answer
The rate at which work is done; P = W/t or P = F·v
