Newton’s second law relates an object’s acceleration to its mass and the net force acting on it. Does Newton’s second law apply to a situation in which there is no net force? Select the best explanation. A. Yes. The law applies and it tells us that the object has a nonzero acceleration. B. No. The law applies only to situations in which a net force acts. C. No. The law does not apply because a zero net force would produce...
What is the force of gravity between you (still m = 75kg) and the Earth? HINT: you don’t need the mass of the Earth for this, just Newton’s second law!

True or false and why for the following in regards to Newton’s 2nd law: 1. if the net force on an object is tripled and its mass is halved then its acceleration will increase by a factor of 6 2. if the net force on an object is halved and its mass is doubled then its acceleration will stay the same

Which of the following is incorrect concerning Newton's First Law? I know that Newton's first law states an object at rest will remain at rest as long as the net force on the object is zero. I narrowed the questions down to three choices of the five: A) An object can not have a constant speed if the magnitude of net force is greater than zero. B) An object can not have a constant veloocity if the magnitude of net...

A beaker of mass MB, containing volume V of pure water, is at rest on a horizontal scale in a lab. A block of aluminum metal, mass mAl, is hanging from a spring scale and is completely immersed in the water. (a) [10 pts] Draw a fbd of the metal block, and write Newton’s second law, putting in all your forces. (You will need to look up “buoyant force” in Chapter 14, which we skipped.) Draw a fbd of the...
