Jessica Yan Rick St. Denis, Tyler Wiseman 13 September 2012 Projectile Motion: Ball in the Bin Purpose: The purpose of the experiment is to determine the velocity of a ball launched from the Projectile Launcher device, and then to use that velocity to find where on the floor the ball will land given a specific angle. Theory: Two-dimensional motion is as it sounds, made of the two components of Vertical velocity and Horizontal Velocity. Horizontal Motion can be described as constant, neglecting air resistance, and Vertical Motion is characterized by the acceleration of gravity pulling at 9.8m/s². In this particular experiment, the total velocity will be split into the two components in order to find the time in the air, and horizontal distance from the launcher. The motion of these components can be described as d=vt for constant horizontal motion, and d=1/2at² + Vit.
Force Table Vectors I. Abstract: From chemical formulas and morality to vectors and forces equilibrium is a term used when the system comes to a complete balance on both sides and no changes occur. This is a critical point where balance is found in nature. In this lab equilibrium is calculated and found using different masses on a force table. A force table is a big compass with degrees marked off to form a circle, wheels are placed at certain points and a string is attached to 3 weights. These weights hang off the sides of the wheels and pull on the string at different angles, the objective is to find the point at which all the weights pull on each other so the center of the string is in the center of the force table.

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?
Which of the following diagrams best represents the directions of the actual forces acting on the box as it moves upward after the push? 3. An ideal spring obeys Hooke's law, F = kx. A mass of 0.50 kilogram hung vertically from this spring stretches the spring 0.075 meter. The value of the force constant for the spring is most nearly (A) 0.33 N/m (B) 0.66 N/m (C) 6.6 N/m (D) 33 N/m (E) 66 N/m 4.
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.
Newton’s Laws apply to a bridge. The first law states an object in motion stays in motion, an object at rest stays at rest unless acted upon by an outside force. A bridge does not move, or at least it shouldn’t. The only thing in motion is the wind being acted on the bridge while it stays at rest. Newton’s second law is F=ma, which means that the force is equal to the mass and acceleration.
Potential energy is the energy an object has because of its position in relatibn to other objects. Kinetic energy is energy associated with a moving object. (p. 27). 24. According to the First Law of Thermodynamics, energy cannot be created or destroyed.
Procedure 3: The Compound Pendulum The aim of this experiment is to determine the value of the acceleration due to gravity by measuring the period of oscillation of the pendulum when suspended from different distances from its centre of mass. A pendulum consisting of any swinging rigid body which is free to rotate about a fixed horizontal axis is called a compound pendulum. This experiment had to be carried out at Glasgow University as the required equipment was not available at school. Procedure 1) The pendulum was balanced on a large brass knife edge to determine the position of the centre of mass of the pendulum. 2) The larger moveable knife edge was then clamped to the pendulum, at a small distance (1cm) above the centre of mass.
