PHYS 284 ALL FINAL EXAM Q&A
CONCORDIA UNIVERSITY UPDATED
REVIEW COLLECTION 2026 QUESTIONS
WITH CORRECT SOLUTIONS GRADED A+
⩥ Force of Gravity Between Two Objects. Answer: Units of G =
N∗m²/kg²
⩥ Kinetic Friction. Answer:
⩥ Static Friction. Answer:
⩥ Uniform Circular Motion - Velocity. Answer: Velocity vector is
constantly changing and is tangential to the circle of motion
⩥ Centripetal Acceleration. Answer: The acceleration vector always
points toward the center of the circle and constantly changes direction as
the object moves.
⩥ Centripetal Force. Answer:
, ⩥ Torque. Answer: θ = angle between F and the lever arm. (Max force at
sin90° = 1) By convention, clockwise rotation is negative,
counterclockwise rotation is positive.
⩥ Work-Energy Theorem. Answer:
⩥ Kinetic Energy. Answer: SI Unit for KE (all energy) = Joules =
kg∗m²/s²
⩥ Work. Answer: θ = angle between F and the displacement vector. Only
forces (or components of forces) that are parallel or anti-parallel to the
displacement vector will do work. Max work at cos0 or cos180 = 1 or -1.
⩥ Gravitational Potential Energy. Answer:
⩥ Conservation of Energy. Answer:
⩥ Power. Answer: SI Unit for Power = Watt = J/s = Energy
consumption, transfer or transformation per unit time
⩥ Momentum. Answer: Momentum is measured in kg∗m/s
⩥ Conservation of Momentum. Answer: For elastic and inelastic
collisions
