Newtons Second Law (GCSE Physics)

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?

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

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

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?

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

A student pushes a toy car of mass 2.0 kg so that it accelerates at 1.5 m/s^2. According to Newton’s Second Law, what is the resultant force on the car?

Which of these scenarios directly illustrates Newton’s Second Law?

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?

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?

Two forces of 8 N and 5 N act in the same direction on a mass of 3 kg. What is the acceleration?
