6. An entity in translational equilibrium may not be rotating.

  • False
  • True

7. The equation defining an impulse is...?

  • ΔF = (Δtv) / m
  • ΔF = (Δmv) / (Δt)
  • ΔF = (Δmt) / (Δv)
  • ΔF = (Δt) / (Δmv)

8. Newton's second law of motion states...?

  • Equal and opposite forces cancel when they are of the same type and acing on two different entities
  • For a system of isolated bodies the total momentum is the same
  • F ∝ Δmv ∝ a ∝ -m (given that (Δmv) or (a) is in the same direction as the force)
  • A body will remain stationary or moving with constant velocity unless a force is applied to the body

9. Newton's third law of motion states...?

  • A body will remain stationary or moving with constant velocity unless a force is applied to the body
  • Equal and opposite forces cancel when they are of the same type and acing on two different entities
  • F ∝ Δmv ∝ a (given that (Δmv) or (a) is in the same direction as the force)
  • For a system of isolated bodies the total momentum is the same

10. The momentum of a system is conserved if...?

  • the forces acting on the system are in equilibrium
  • no friction forces act within the system
  • no external forces act on the system
  • no kinetic energy is lost or gained by the system

11. The law of Conservation of Momentum states...?

  • Equal and opposite forces cancel when they are of the same type and acing on two different entities
  • For a system of isolated bodies the total momentum is the same
  • A body will remain stationary or moving with constant velocity unless a force is applied to the body
  • F ∝ Δmv ∝ a (given that (Δmv) or (a) is in the same direction as the force)
