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?

A box on a level floor has a horizontal push of 50 N and friction of 30 N opposing the motion. If the box mass is 10 kg, what is the acceleration?

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

A net force of 0.5 N acts on a 250 g toy. What acceleration results?

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 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 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?

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

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

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?
