Question : i graphed an acelleration graph and every .1 sec the velocity increased ten then in another .1 secs it decrased by ten. The shape of the graph went up and down. Is this accelleration graph an example of uniform motion. so ijn .1 secs the velocity was 76 then in .2 secs it was 70 then in .3 secs it went back to 76 and so on. Is this uniform motion? Why? How do you know by looking at the graph? Thanks a lot
Answer : Uniform motion would always have an acceleration of 0, and a constant velocity. You know that this isn't uniform motion, because when you look at the acceleration graph, it's not at 0.
Question : please help answer these!
what are Newtons 3 laws of motion. what are each of their significance?
what is gravity? what factors determine the pull of gravity on an object? why do 2 objects of diff, masses fall at equal velocities? what is the distinction between weight and mass? does weight or mass change on different planets? why?
know the different forms that energy can take
THANK YOU SO VERY VERY MUCH!!!!YOU ARE A LIFE SAVER!!!!
Answer : You got alot of question : I will answer the first one.
what are Newtons 3 laws of motion?
I. Every object in a state of uniform motion tends to remain in that state of motion unless an external force is applied to it.
II. The relationship between an object's mass m, its acceleration a, and the applied force F is F = ma. Acceleration and force are vectors (as indicated by their symbols being displayed in slant bold font); in this law the direction of the force vector is the same as the direction of the acceleration vector.
III. For every action there is an equal and opposite reaction.
Question : the concept is from physics, reveal the truth and misconception related to it
Answer : no it is not...
on one hand, uniform motion can be termed as 'uniform velocity' that is moving at a constant velocity
& on the other hand, 'uniform acceleration (or retardation / decceleration)' is the constant incerament (or decrement)' the given velocity.
so, uniform velocity can be exampled for no or Zero acceleration (or retardation / decceleration)
