Hi, I have one try left for my homework and I need help with my reasoning. Can anybody help?
A) Mass is a measure of the inertia of a body. False
B) In order not to slow down, a car moving at a constant velocity needs a small net force applied. True? This would only be false in an ideal, fricitionless setting right?
C) An object's velocity will change if a net force acts on the object.True
D) If a net force acts on an object, the object's speed must change. ?
E) The net force which acts on an object which remains at rest is zero.
True because F=ma and if a=0 then F=0?
F) If two objects have the same acceleration, they must be under the influence of equal forces. False, they could have difference masses, therefore different Forces
