Newtons Second Law (GCSE Physics)

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 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 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?

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

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

A 5 kg object experiences a resultant force of 20 N. What is its 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?

A cyclist and bicycle have a combined mass of 80 kg and accelerate at 1.25 m/s^2. What is the resultant horizontal force?

A student hangs two different masses from an identical spring and measures initial acceleration when released. Which change would show Newton’s Second Law?

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 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?
