Question 1

What does Newton's Second Law state?

  • A. Force is equal to mass times velocity
  • B. Acceleration is inversely proportional to mass
  • C. Acceleration is directly proportional to net force
  • D. Mass does not affect acceleration

💡 Hint: Think about the formula F_net = ma.

Question 2

True or False: A large mass will result in higher acceleration with a given force.

  • True
  • False

💡 Hint: Consider how mass affects the acceleration.

Challenge Problems

Push your limits with challenges.

Question 1

A skateboarder with a mass of 60 kg pushes off the ground and accelerates at 3 m/s². Calculate the net force exerted by the skateboarder on the ground.

💡 Hint: Use the formula F = ma to relate mass and acceleration.

Question 2

If two cars, Car A with a mass of 800 kg and Car B with a mass of 1200 kg, experience the same net force of 3000 N, calculate their accelerations and compare them.

💡 Hint: Apply F = ma for both cars separately and analyze the relationship.
