In the lab, you looked at speed-time graphs to determine the acceleration of the cart for each of the three fan speeds.
What was the acceleration of the cart with Low fan speed?
What was the acceleration of the cart with Medium fan speed?
What was the acceleration of the cart with High fan speed?
1 cm/s2
cm/s2
cm/s2

Velocity is a description of both speed and direction, therefore it - a vector - a force arrow - the same as acceleration - a magnitude

A30 kg weight lies on top of a massless piston of area a = 0.01 m2 the exterior air is at a (constant) p =1 atm and t = 27 c. the interior gas is 0.4 moles of (ideal) n2 and it has initial temperature 27.00 degrees c. 1. what is the initial pressure in the interior? a. 29.4 kpa b. 130.7 kpa c. 101.3 kpa the next three questions concern what happens when an amount of heat q is slowly added to the interior, raising the piston by 1 mm and raising the interior temperature to 27.40 c

If a simple machine reduces the strength of a force, what must be increased?
