How is force calculated?
Force in terms of newtons is expressed in the equation f=ma, that is, force (newtons) = Mass (kilograms) x Acceleration (MS-2, meters per second per second). This refers to the force needed to exert on something to increase its speed disregarding friction as a form of negative force. To work out the force applied by something when it causes impact, Forcei = mass x speed. Say a 100kg object is travelling at 10ms-1 , it is exerting a force of 1000 newtons upon impact, now if it impacts with another person of mass of 50kg, and stops completely, that other person will travel at a speed of 20ms-1 in the same direction that the original person was travelling. hope this helped.
You cover 10 meters in a time of 1 second. Is your speed the same if you cover 20 meters in 2 seconds?
Yes, as speed=distance/time. Therefore 10/1 = 10ms-1 and also 20/2 = 10ms-1
What determines the magnitude of the normal force?
The normal force if the force of one object holding up anothe. Ex. a block of wood on the ground. The normal force is the force applied to the wood to prevent it from sinking. In other words, it is the objects weight. W=mg, where W=weight, m=mass, g=force of gravity.
What can you pick up by exerting 1 newton?
The short answer is:A mass with a weight of 1 Newton such as a small apple.A longer answer is:On average a mass of 101.9g on Earth although it will depend a bit exactly where you are, the force of gravity varies a little from place to place even on the surface of the Earth. On the moon it would be a mass of about 616.5g.In high school the acceleration due to gravity on Earth is often simplified to 10ms-2 rather than the average value of 9.81ms-2. If we use 10ms-2 you get an answer of 100g.
What is the momentum of a 25kg sheep traveling east at 10ms?
The sheep's momentum vector has a magnitude of 250 kilogram-meters per second,and a direction of east.
An RC circuit has a time constant of 10ms and an applied voltage of 15V What is the voltage on the capacitor after one time constant?
About 5.5 volts.
How can you determine the amount of force exerted?
To find the force on an object, you multiple the mass of the object by its accelerationFor example, let's say a ball is moving at 7 m/s squared and has a mass of12 kg.The formula for force is: F = maF = 12 kg x 7 m/s squaredF = 84 N ( the unit for force is N, which is Newtons)*Be careful, an object does not "have a force". A force is an action that can modify the shape of an object and/or modify its velocity. Therefore, you do not calculate the force of an object, but the force required to give it a certain acceleration.
Which is bigger 0.05 millisecond or 0.05 centisecond?
centisecond = cs millisecond = ms 1cs = 10ms 0.05ms x 1cs/10ms = 0.005cs The 0.05cs is larger than the 0.05ms.

How do you measure mechanical frequency?
I assume you mean measure the frequency of vibration of a mechanical system or part. You use a stroboscope, which is a light that flashes briefly and rapidly. You shine the light on the object and adjust the frequency of the strobe by turning a dial until the object stops moving. You then read the dial to determine the frequency. there are steps you have to take to avoid synchronizing to a subharmonic of the base frequency. For example, if the object is vibrating at 100Hz (10ms), running the strobe at 50hz will also stop the motion, as it will pick up every other cycle.
