Question

Which would require a greater forcd accelerating a 1kg mass at 10m per second sauare or 2kg mass at 4m per second square?

Answer 1

Force = mass × Acceleration

Force on the 1kg mass :

1 × 10 = 10N

Force on 2 kg mass :

2 × 4 = 8 N

10 N > 8N

We therefore need a greater force to accelerate the mass of 1 kg at 10 m/s²
