Try each question first, then open the answer. Explanations are included.

1. What term describes the force that opposes relative motion between two surfaces in contact?

  1. AFriction
  2. BNormal force
  3. CTension
  4. DGravity
Show answer

Answer: A

Friction is the force that resists the relative motion or tendency of such motion between two surfaces in contact.

2. What is the SI unit of force?

  1. APascal (Pa)
  2. BJoule (J)
  3. CWatt (W)
  4. DNewton (N)
Show answer

Answer: D

The SI unit of force is the Newton, named after Sir Isaac Newton.

3. What term describes the force exerted by a stretched string, rope, or cable?

  1. ANormal force
  2. BFriction
  3. CTension
  4. DBuoyancy
Show answer

Answer: C

Tension is the pulling force transmitted through a string, rope, cable, or similar object when it is pulled taut.

4. What term describes the upward force exerted by a fluid that opposes the weight of an object immersed in it?

  1. ABuoyant force (Buoyancy)
  2. BTension
  3. CNormal force
  4. DFriction
Show answer

Answer: A

Buoyant force is the upward force exerted by a fluid on an immersed object, equal to the weight of the fluid displaced (Archimedes' Principle).

5. What term describes the tendency of an object to resist changes in its state of motion?

  1. AVelocity
  2. BAcceleration
  3. CMomentum
  4. DInertia
Show answer

Answer: D

Inertia is the inherent tendency of an object to resist changes in its state of motion (whether at rest or moving), directly related to its mass.
