For most purposes Newton's laws of gravity apply, with minor modifications to take the general theory of relativity into account. 2. Inertia - A property of matter by which it continues in its existing state of rest or uniform motion in a straight line, unless that state is changed by an external force. 3. Potential Energy - Is the energy stored in an object due to its position in a force field or in a system due to its configuration.
Inertia Worksheet Answers 1. Imagine a place in the cosmos far from all gravitational and frictional influences. Suppose that you visit that place (just suppose) and throw a rock. The rock will a. gradually stop. b. continue in motion in the same direction at constant speed.
So you may be able to argue it shows that f is proportional to Mass x acceleration (but to be honest I think that would be stronging it a bit - balloons don't seem to give very constant thrust. First, you have to know the 3 laws of motion. 1. "A body continues to maintain its state of rest or of uniform motion unless acted upon by an external unbalanced force." 2.
Also this lab teaches about measurement uncertainty can be calculated using the percent error equation. These are the purposes of the lab. My hypothesis of this experiment is that the velocity of an object, the ball rolling down a ramp or falling down, changes at a constant rate, thus uniform acceleration occurs. Acceleration is a vector quantity that is defined as the rate at which an object changes its velocity over time. An object accelerates if its velocity is constantly changing, also known as speeding up or slowing down.
The maximum frictional force that must be overcome before movement is able to begin is μsFN. If you apply a constant force to pull an object along a horizontal surface at a constant speed, then the frictional force opposing the motion is equal and opposite to the applied force, Fp. Therefore, Fp = Ff. The normal force is equal and opposite to the object’s weight when the object is on a horizontal surface and the applied force is horizontal. The question to be answered by performing this lab is how can the coefficient of static and kinetic friction be determined for an object on a horizontal surface?
The distance between the forces is given by the Coulombs law through the use of the formula F=kq1q2/r2.0.1newtons = 8.99*109*3.2*10-6*7.7*10-7/r2 R= 555.78 Answer to question 3 • Potential difference between the two plates is equal to velocity which is equal to 6.0*106m/s • Force = mass *acceleration = 1.4*10-13*6.0*106 = -8254 nektons The speed of the particles are computed by the formula V=ED. This is equal to 8.5*10-6*0.15. This is equal to 84.1 Answer to question 4 Voltage = current *resistance. This implies that in this case while V is 5.0 and resistance is 1.0*103, current will be equal to 5/1.0*103, = 500 amps B the direction of the conventional current provides the electric charge movement from the positive side of the battery to its negative side as in indicated in the diagram below Answer to question 5 • This section focuses on the equivalent resistance of a circuit. The equivalent resistance will be equal to (5.0*102+1.00*103)2.
It is called Newtonian, because it began from the Newtonian discovery of the laws of gravity and world motion. Newton’s law was composed of three laws. And form a clear description of all possible motions, where as Ptolemy was the baseline and gave the first guideline about the universe for almost 1500 years. Newton’s universe was very clear and concise. It told us the only way to change the motion of an object it to apply a force.
Boyle scientifically varied the pressure and measured the volume of the gas. These measurements were performed using a fixed amount of gas and a constant temperature. In this way Boyle was able to examine the pressure-volume relationship without complications from other factors such as changes in temperature or amount of gas. Boyle’s law states that at constant temperature for a fixed mass, the absolute pressure and the volume of a gas are contrarily proportional. The law can also be stated in a slightly different manner, that the product of absolute pressure and volume is always constant.
