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.
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. This enabled the group to determine the spring constant k. B. Derivation of Equations Definitions To gain a better understanding of the terms used here
To analyse this further, we can observe Newton’s first law of motion. Newton’s law describes how an object in motion, remains in motion. This is why the roller coaster continues going up the slope [1]. However, the KE is lost, as gravity takes effect and
Galileo would say there is a friction force that brings the ball to rest. Newton will say same as Galileo. 3. Answer the following questions: 1. Explain mechanical equilibrium.
A roller coaster involves plenty of physics knowledge join together and makes it function. A sample of the roller coaster has shown above. In the beginning, carts are slowly moving to the top place by some mechanical devices like chain and motor (external energy force. Then, the potential energy is sufficient and starts to transfer the energy for the rest of motions. The principle of conservation energy states from ESA study guide: “energy cannot be created or destroyed but can be changed from one form to another.” When carts are on the point 1(top), the quantity of the gravitational potential energy is maximised, according to the formula of gravitational potential energy Ep=mgh.
For collisions, the momentum before the collision is equal to the momentum after the collision e.g. snooker balls Momentum before collision EQUALS Momentum after collision p=mv p=0 p=0 p=mv Another example is cannon before being fired and after being fired. Before the cannon is fired the momentum is zero, after it is fired the cannon ball moves forward and the cannon moves back. The momentum of the cannon ball is the same as the momentum of the cannon moving backwards. In this sort of example you should choose one direction to be positive and the other direction to be negative.
When an object demonstrates a constant acceleration, the velocity of the object will change either increasing or decreasing with the same rate while traveling in the same direction. During this experiment, we used the equationH=12gt2 . From this equation, h denotes height, g represents acceleration due to gravity (9.8 m/s2), and t stands for time. The variables in this equation are all accounted for with the exception of g. The height is the distance from the bottom of the ball to the top of the pad (measured in meters). The time (t) corresponds to how long it took the ball to travel after being released from the clip to the pad
Using mathematics, he showed that a single force keeps the planets in their orbit around the sun. He called this force gravity and then created Newton’s law of Motion. Law one states that an object at rest will remain at rest, and an object in motion will remain in motion, at a constant speed unless or until outside forces act upon it .Law two states that the net force acting upon an object is a product of its mass multiplied by its acceleration. Law three states that when one object exerts a force on another, the second object exerts on the first a force equal in magnitude but opposite in
Newton’s second law of motion is expressed as a mathematical equation: Fnet = ma (Force = mass*acceleration) A significant notion of this equation is that an object accelerates in the direction of the new force, and acceleration is created by the net force. The SI unit for force in the above equation is Newton (N), SI unit for accelerations is metre per second squared (m/s2) and the SI unit for mass is kilograms (kg). The objective of this experiment was to show the relationship between acceleration and force in a frictionless environment and to show the concept of mass (Lab#1). Other equations used in this experiment were: V22 = V12 + 2ad; used to find the acceleration for each weight V1 = Lt1 and V2 = Lt1; both used to find the acceleration Materials * Two vernier photogate timers * String * Glider * Blower * Air—cushioned track * Weights and Hanger * Pulley and clamps * Vernier Lab Pro Procedure and Observations 1. Two photogate timers, 60 cm apart, were set over the air track.
