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