1.164m/2.43s = 14 m/s 1.264m/4.4s= 14.5 m/s 1.3Tension and velocity are positively correlated but the relationship may not be linear. 1.4The more dense the string, the lower the velocity. This is because it would take m
Part 1 A: start back, wait, move forward, stop C: Movement away at a constant speed
B: start walking back at a constant speed, stop, then walk forwards at a constant speed
D:Start back and immediately move forward slowing down, then moving away at
Newtons first law of motion:
An object at rest remains at rest, and an object in motion continues in motion with constant velocity (that is, constant speed in a straight line), unless it experiences a net external force.
No external force or acceler
