Question 1
What does Newton's Second Law state?
- Object at rest stays at rest.
- Force equals mass times acceleration.
- For every action
- there is an equal and opposite reaction.
💡 Hint: Remember the formula related to force.
Question 2
True or False: A heavier object requires more force to achieve the same acceleration as a lighter object.
- True
- False
💡 Hint: Consider how mass affects acceleration with constant force.

Challenge Problems
Push your limits with challenges.
Question 1
A cyclist accelerates from 0 to 5 m/s². If the cyclist has a mass of 70 kg and every second, 20 N of force is applied, calculate the distance traveled in 3 seconds.
💡 Hint: Find acceleration first, then use the kinematic equation for distance.
Question 2
If a car of mass 1,200 kg accelerates uniformly to reach a speed of 80 km/h (22.22 m/s) and takes 10 seconds to do so, what is the net force acting on the car?
💡 Hint: Convert speed to m/s, then use the acceleration to find force.
