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?

Which equation best expresses Newton’s Second Law?

If the resultant force on an object is zero, which statement is true about the object?

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

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?

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 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?

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