The 20 questions

  1. According to Newton's First Law, what does a stationary object do with zero resultant force?

    • Slow down
    • Remain stationary
    • Accelerate forwards
    • Move backwards

  2. According to Newton's First Law, what does a moving object do with zero resultant force?

    • Change direction
    • Speed up
    • Slow down
    • Constant velocity

  3. What is required to change the velocity of an object?

    • High mass
    • Balanced forces
    • Resultant force
    • Zero force

  4. Why does a car travel at a steady velocity on a straight road?

    • Zero drag
    • Forces balance
    • Infinite momentum
    • Unbalanced forces

  5. Why does a puck slide across smooth ice at nearly constant velocity?

    • Negligible friction
    • Zero mass
    • Large driving force
    • High friction

  6. Why do passengers lurch forward when a bus brakes suddenly?

    • Inertia
    • Magnetic force
    • Gravity
    • Air resistance

  7. Which scenario involves a resultant force of zero?

    • Accelerating car
    • Rocket launching
    • Book on table
    • Falling apple

  8. A ball rolls at constant velocity. The forces acting on it are:

    • Only one force
    • Unbalanced
    • Balanced
    • Zero in mass

  9. A spacecraft far from any planet has its engines off and no forces act. Its velocity stays constant. The law being used is:

    • Newton's First Law
    • Newton's Third Law
    • Conservation of energy
    • Newton's Second Law

  10. What is the tendency of objects to continue in their state of rest or uniform motion called?

    • Inertia
    • Acceleration
    • Momentum
    • Gravity

  11. (HT only) A passenger keeps moving forward when a fast-moving car brakes. This best demonstrates:

    • Inertia
    • Friction
    • Gravity
    • Terminal velocity

  12. (Harder) A vehicle moves at steady speed with a driving force of 1500 N. The resistive force is:

    • 3000 N
    • 1500 N
    • 750 N
    • 0 N

  13. (Harder) An object moves at constant velocity. A car's resistive force is 800 N at steady speed. The driving force must be:

    • 0 N
    • 800 N
    • 1600 N
    • 400 N

  14. An object at rest has a 10 N force left and 10 N right. What does it do?

    • Remain stationary
    • Accelerate left
    • Move at 10 m/s
    • Accelerate right

  15. A lorry travels at constant velocity on a motorway. Its driving force balances the resistive forces. Its velocity is:

    • Increasing
    • Constant
    • Decreasing
    • Zero

  16. What must act on an object to change its direction?

    • Resultant force
    • Constant mass
    • Zero friction
    • Balanced forces

  17. A sledge slides across frictionless snow. What happens to its speed?

    • Drop to zero
    • Rapidly increase
    • Gradually decrease
    • Remain constant

  18. (Harder) A 4 N force pushes right on an object. A 4 N friction force and a 1 N air resistance both act left. The resultant force is:

    • 1 N to the left
    • 9 N to the left
    • 0 N
    • 1 N to the right

  19. (Harder) An object moves at 6 m/s and the resultant force on it is zero for 10 s. Its velocity after 10 s is:

    • 0 m/s
    • 6 m/s
    • 16 m/s
    • 60 m/s

  20. What property of passengers causes them to lurch forward when a car stops?

    • Gravity
    • Inertia
    • Weight
    • Momentum
