must have constant velocity. must have zero momentum. 10. The inertial mass of a body may be defined as A. B. C. D. the ratio of the resultant force acting on the body to its acceleration.
Don’t confuse mass and weight as mass is actually the amount of ‘stuff’ that makes up an object measured in kilograms. Weight is the force calculated by Weight (N) = Mass (kg) x Gravitational field strength (N/kg) W m The gravitational field strength on Earth is taken as 10N/kg. A resultant force is the sum of forces acting on an object. 2N 4N 4N Resultant force = 2N + 4N = 6N to the right g 2N
Description and Theories A. Principles and Theories Used to Obtain our Result An conventional spring, when subjected the weight (w=mg) of an object at one of its terminations, will displace a certain distance, x, with an equal and opposite force, F, being created in the spring of which opposes the pull of the weight. This conventional spring will become significantly distorted if it is subjected to a large enough weight and the force, F, will only be able to return the spring to its original configuration once the burden is removed. The force that will restore the spring to its original configuration is directly proportional to the displacement that occurred. The following equation represents this relationship where k denotes the spring constant or stiffness of the spring, F=-kx Since x symbolizes the displacement or change in the length of the spring the above equation can now be surmised in the following manner, F=mg=-k∆l This new form makes it evident that a linear proportion exists between the plot of F as function of changing in length, ∆, thus confirming the spring does in fact obey Hooke’s Law.
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.
b. continue in motion in the same direction at constant speed. A: According to Newton's first law, the rock will continue in motion in the same direction at constant speed. 2. A 2-kg object is moving horizontally with a speed of 4 m/s. How much net force is required to keep the object moving at this speed and in this direction?
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.
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?
Mathematical Relationships The relationship between acceleration, velocity and distance will help us to model the performance of the car. Relation of force (N) to mass (kg) and acceleration (m/sec2): Relation of velocity (m/sec) to acceleration (m/sec2): Relation of distance (m) to velocity (m/sec): Drag and Wind resistance The effect of wind resistance will be modelled as the additional force which takes effect at velocities greater than v1. According to the equation Fd = Fd0 (1 + b(v �� v1)2) the drag force will increase for velocities v > v1. In this case study there will be a low velocity drag force acting on velocities 20 m/s or less and an
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.
Inventions and laws of Sir Issac Newton and Johannes Kepler Kepler is Johannes one name that will always be remembered in the field of astronomy. He was not only a great astronomer ,but famous mathematician and astrologer also. The German astronomer was the first person to explain planetary motion. He gave three laws of planetary motion .Which was the basic of Isaac Newton law of gravitation, Sir Issac Newton universally considered to be one of the greatest and most influential scientists .he was an English mathematician and physicist, well known for his contributions to physics and mathematics . He also invented the geometric graph of tangent (differentiation) and formulated the three laws of motion and the universal theory of gravitation.
