If a force v time graph made a sine curve, then the acceleration v time would create a sine curve too correct? However, the velocity v time curve would look like a pi/2 shift to the right? Are these thoughts correct?
I'm starting to understand, but I'm still a little iffy on the negative force. Say a cart moves towards the origin slowing down and at a steady rate, it turns around after 2 seconds and then moves away from the origin speeding up at the same steady rate. The v vs t graph would look like a steady positive slope from negative to positive where x=0 at 2 seconds...what would force look like?
when the acceleration vector is positive, it means you go faster and faster. When it is negative you are slowing down. Same thing for the force-vector since it is the acceleration vector multiplied by a positive constant (the mass)
when two equal forces are applied to an object...one form the left and the other from the right...the object is kept stationary, however, the new force would be the combination of both forces from the left and right correct?
