Question

unit 2 test: forces and motion (10/15)
what does an object with more mass require to accelerate, according to newtons second law of motion?
more force
less force
more distance
less speed

Explanation:

Newton's second law of motion is \(F = ma\) (where \(F\) is force, \(m\) is mass, and \(a\) is acceleration). If we want to achieve a certain acceleration \(a\), when the mass \(m\) increases, to keep the equation valid, the force \(F\) must increase. Distance and speed are not directly related to the relationship in Newton's second law for the question of what is required to accelerate an object (the law focuses on force - mass - acceleration relationship).

Answer:

more force
