Happy Bday dude
my gift to you
Weight (force of gravity) decreases as you move away from the earth by distance squared.
Mass and inertia are the same thing.
Constant velocity and zero velocity means the net force is zero and acceleration is zero.
Weight (in newtons) is mass x acceleration (w = mg). Mass is not weight!
Velocity, displacement , momentum, force and acceleration are vectors.
Speed, distance [d], time, and energy (joules) are scalar quantities.
The slope of the velocity-time graph is acceleration.
