for a body that is undergoing centripetal acceleration. Background Information An object moving in the same direction is not necessarily undergoing acceleration. If the object changes speed while moving in the same direction there is acceleration (or deceleration). On the other hand‚ if the object moves at a constant speed in the same direction‚ there is no acceleration. This does not mean that constant speed always indicates no acceleration‚ however. An object that moves at a constant

Circular Motion and Gravitation Circular motion is everywhere‚ from atoms to galaxies‚ from flagella to Ferris wheels. Two terms are frequently used to describe such motion. In general‚ we say that an object rotates when the axis of rotation lies within the body‚ and that it revolves when the axis is outside it. Thus‚ the Earth rotates on its axis and revolves about the Sun. When a body rotates on its axis‚ all the particles of the body revolve – that is‚ they move in circular paths about

In the year of 2003‚ a 16-year-old young man named Terrance Graham attempted to rob a restaurant. Graham was charged as an adult facing a life sentence without parole. Graham was offered one year in jail and two additional years of probation by his prosecutor given

Chilled cake or fridge cake is a kind of homemade cake that is convenient for people to make it and serve as a dessert since it doesn’t need to use flours or other ingredients and other materials such as oven. It is simply made by mixing the cream‚ layering the biscuits and putting on the toppings. That is why people are fond of creating different recipes for graham cakes because it

This article is about pendulums. For the band‚ see Pendulum (band). For other uses‚ see Pendulum (disambiguation). "Simple gravity pendulum" assumes no air resistance and no friction. | An animation of a pendulum showing the velocity and acceleration vectors (v and A). | | A pendulum is a weight suspended from a pivot so that it can swing freely.[1] When a pendulum is displaced from its resting equilibrium position‚ it is subject to a restoring force due to gravity that will accelerate it

determine the minimum speed required to clear 8m in 2.02 s just use D/T= 8/2.02= 3.96 m/s horizontally to clear 8 m from 20 m vertically. 5) Using acceleration = force * mass‚ we know the car had a force of 5000N‚ and a mass of 1500kg. 5000/1500 = -3.33 m/s deceleration. It took 5.6 seconds for the car to decelerate to 0‚ so multiply the deceleration/acceleration with the amount of time to obtain the initial speed of the vehicle. 3.33 * 5.6 = Initial speed of 18.65 m/s 6) Weight is equated as mass * gravity

law of motion‚ Acceleration is produced when a force acts on a mass. The greater the mass is‚ the grater the acceleration is needed to move forward. This law basically states that a force applied to the objects changes its velocity overtime in the direction of the force that is applied‚ the acceleration is directly proportional to the force‚ as an example‚ if pushing on an object‚ causing it to accelerate‚ and then you push‚ the same object three times harder‚ the acceleration will be three times

vertical motion are independent of each other; that is‚ neither motion affects the other. Acceleration Since there is no acceleration in the horizontal direction velocity in horizontal direction is constant which is equal to ucosα. The vertical motion of the projectile is the motion of a particle during its free fall. Here the acceleration is constant‚ equal to g.[1] The components of the acceleration: a_x = 0 ‚ a_y = -g . Velocity The horizontal component of the velocity remains unchanged

and Gravity Define mass‚ weight‚ force‚ and acceleration. Mass – A measure of the total amount of material in a body‚ defined either by the inertial properties of the body or by its gravitational influence on other bodies. It is proportional to‚ but not the same as‚ its mass Force – A quantitative description of the interaction between two physical bodies‚ such as an object and its environment. Force is proportional to acceleration. Acceleration – A vector quantity that is defined as the rate
