  • Gravity
  • Air resistance
  • Magnetism
  • Friction

# 6

Pilihan ganda

All vehicles have a top speed. This is when:

  • the air resistance is the same as the force from the engine.
  • the drag and friction forces balance the maximum force from the engine.
  • the force from the engine balances friction in the wheels.
  • the drag forces balance the friction forces.

# 7

Pertanyaan jawaban singkat

What is the term for the force that always acts in the opposite direction to the motion of an object moving through air?

  • air resistance

# 8

Pilihan ganda

Balanced forces:

  • make objects speed up
  • make objects slow down.
  • do not change the speed of moving objects
  • only affect stationary objects

# 12

Pilihan ganda

What happens if friction is completely removed between a car’s tires and the road?

  • The car would not be able to move forward, turn, or stop effectively, losing all control.
  • The car would accelerate much faster than usual.
  • The car would become more fuel efficient while driving.
  • The tires would grip the road even better than before.
