Newtons Second Law (GCSE Physics)

A car of mass 1200 kg accelerates from 0 to 10 m/s in 5 s. What average resultant force acted on the car?

Why does a heavier car require a larger resultant force to achieve the same acceleration as a lighter car?

An object of mass m has acceleration a under force F. If mass becomes 3m and same force applied, what is new acceleration?

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

A fighter jet increases its acceleration by reducing mass via fuel burn while thrust remains constant. How does Newton’s Second Law explain the change in acceleration?

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

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?

Which equation best expresses Newton’s Second Law?

How does increasing the mass of an object affect its acceleration when the same resultant force is applied?

A rocket accelerates upwards by 20 m/s^2. If the thrust minus weight equals the resultant force, and the rocket mass is 2000 kg, what is the resultant force?

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