Uniformly Accelerated Movement Abstract
Acceleration is defined as the rate of change of velocity with respect to time in a given direction. Uniformly accelerated movement is movement that always has the same acceleration, meaning that it is a constant force; the force of gravity is the classic example. We will prove that acceleration with a constant force of gravity can help determine velocity and distance at a certain time using derived basic equations. The data collected determines a 3.78% of error that proves the equations are correct, and that its value could have been affected by errors in the process.
1 Introduction
Acceleration is defined as the rate of change of velocity with respect to time in a given direction. It is a vector quantity that is defined as the rate at which an object changes its velocity [3]. An object is accelerating if it is changing its velocity. The next equations describe velocity and acceleration:
a = v/s (1)
where v = m/ s (2)
where m = distance in meters; s = time in seconds.
Since acceleration is a vector quantity it has magnitude and direction [3].
Uniformly accelerated movement (UAM) is movement that always has the same acceleration, meaning that it has a constant equal force. An object with a constant acceleration should not be confused with an object with a constant velocity; an object with a constant velocity is not accelerating.
The perfect example of constant force is gravity (g Earth = 9.81 m/s2), which is the force of attraction between all masses in the universe, and in this cases specially the attraction of the earth's mass for bodies near its surface [4]. If an object is held motionless in a uniform gravitational field it will fall in a constant acceleration, this means that every second that the object falls its velocity will

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.

1885 Words | 8 PagesAlso 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.

362 Words | 2 PagesThe 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?

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.

## Boyle's Gas Law

513 Words | 3 PagesBoyle 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.
