Question

according to newtons second law, which object requires the least amount of force to accelerate?
a bike
b skateboard
c car
d moving truck

Explanation:

Step1: Recall Newton's second law

Newton's second law is \(F = ma\) (where \(F\) is force, \(m\) is mass, and \(a\) is acceleration). If we assume the acceleration \(a\) is the same for all objects (since the problem is about comparing forces to accelerate), then \(F\propto m\) (force is proportional to mass).

Step2: Compare masses of objects

Among a bike, skate - board, car, and moving truck, a skateboard has the smallest mass.

Answer:

B. skateboard
