A meter stick is held vertically above your hand, with the lower end between your thumb and first finger. On seeing the meter stick released, you grab it with these two fingers. You can calculate your reaction time from the distance the meter stick falls, read directly from the point where your fingers grabbed it. If the measured distance is 18.3 cm, what is the reaction time? |

If you were called upon to balance a meter stick on the palm of your hand, vertically, with a sliding weight attached, where would you place the sliding weight so that it would be easiest to keep the stick from rotating,ie: keep it balanced? [ 1) at the lowest point on the stick, 2) near the middle of the stick, or 3) near the end away from your hand ] . Explain

Problem 1: Reaction Time Figure below shows a simple technique for measuring your reaction time. A friend holds a meter stick vertically, with thumb and forefinger at one end as shown. You then position your thumb and forefinger at the other end, being careful not to touch the meter stick. Your friend releases the stick, and you try to pinch it as soon as possible after you see it begin to fall. After multiple trials you find that the meter...

Phy 1010 – Chapter 2 Activity: Measure your reaction time. Requires a ruler and a friend to help you. Hold the index finger and thumb of your dominant hand about 2.5 cm apart, and have a friend hold a ruler vertically in the space between your fingers and thumb. Note the position of the ruler relative to your index finger. Your friend must release the ruler, and you must catch it (without moving your hand downward) as quickly as you...

Torques and Center of Mass. The
Experiment:
In this experiment, you balance a meter stick, to balance the
meter stick, attach masses at positions until the system is in
equilibrium.
The meter stick acts as if all its mass was concentrated at its
center of mass. With the fulcrum at the center of mass, r (the
distance from the axis of rotation to the place where the force is
applied) is 0, so there’s no torque due to the meter...

You repeat this 5 times, writing down how far the stick has fallen each time. You get 7.0 cm, 16.0 cm, 13.0 cm, 7.0 cm, and 12.0 cm. What is the average distance that the meter stick falls, in meters? The meter stick falls an average distance of meters. (Answer with at least...

Required (hand in) 1. By using a 2-meter stick (like the one in lab) marked in millimeters and a stopwatch that measures to 1/100h of a second, you decide to measure the speed of a motorized toy car that travels at a constant velocity. You measure out a 162.0cm interval with the 2-meter stick and time how long it takes the car to travel that distance using the stopwatch. Repeating the experiment 5 times you get the following time data:...
