Newtons Second Law (GCSE Physics)

If the force on an object doubles while the mass stays constant, what happens to the acceleration?

Why does loading a truck close to its maximum mass increase stopping distances for the same braking force?

If a net force acts on a body for a longer time, how does that affect its change in velocity, assuming mass is constant?

Which equation best expresses Newton’s Second Law?

Which unit is the SI unit of force used in Newton’s Second Law?

A 10 N resultant force produces 2 m/s^2 on object A and 0.5 m/s^2 on object B. How do their masses compare?

A sports car applies a force that produces 6 m/s^2 on an empty car and 3 m/s^2 when loaded. What is the ratio of loaded mass to empty mass?

A drone holds a constant upward thrust producing a net upward force of 12 N and accelerates upward at 3 m/s^2. What is the drone’s mass?

A 0.75 kg ball is thrown and the only horizontal force acting is air resistance of 0.15 N opposing motion. What acceleration does this produce horizontally?

A 4 kg block has three horizontal forces: 10 N right, 3 N left, and 2 N right. What is its acceleration?

A force sensor records a sudden spike when two objects collide and then drops to zero while objects separate. Which Newton’s law explains why the force spike occurs proportional to the masses and accelerations?
