Could you please check my answers and help me out with the last two? Thanxs!


1.Carefully define the following words: distance, displacement, speed, velocity, acceleration. Does it make a difference if we designate distance as "x" or "d"? (I don't understand this question)


2.What is the difference between “inertial mass” as in F=ma, and “gravitational mass” as in F=mg? (This one I don't understand)

3. What is the difference between acceleration “a”, and the acceleration of gravity “g”?

The difference between acceleration “a” and the acceleration of gravity “g” is that acceleration “a” is the time rate of change in velocity, while the acceleration of gravity “g” is the acceleration due to gravity alone.


4.Is acceleration proportional to net force or does acceleration equal net force?

Acceleration is proportional to the net force because any change in one is the same amount of change in the other.

    1. Look up the definitions. It makes no difference what symbol one chooses for displacement.
    2. There is no difference. A given object has the same mass in both equations, whether computing acceleration or gravitional weight.
    3. acceleration is a variable that can take on any value, which depends upon the applied force. g is the rate at which a falling body accelerates near the surface of the Earth.
    4. F = m a
    m is the mass, which is constant. Therefore, for a given mass m, force is proportional to acceleration.
