and every one of us follow. Newton’s first law is law of inertia‚ which is a restatement of Galileo’s idea‚ an object in rest stays in rest or an object in motion stays in motion unless acted upon by an outside force. Newton’s second law states acceleration is proportional to the magnitude of the net force‚ is in the same direction‚ and is inversely proportional to the mass of the object. Newton’s third law‚ action and reaction‚ states for every action there is an equal and opposite reaction. The

seconds‚ the velocity of Billy increases linearly from 0 to about 14 m/s.” One dimensional motion‚ such as a car trip‚ can be described using several different graphs. A velocity vs. time graph can be used to describe both acceleration and displacement. Acceleration is shown by the slope of the graph‚ displacement by the area. Billy and Crystal both took a short car trip along a road heading straight west from their house. They recorded their velocity every second. After they got home‚

MOMENT OF INERTIA Chua‚ Richard Janssen J.‚ PHY11L/A3 chardsenchua77@yahoo.com Abstract The moment of inertia‚ or also known as the rotational inertia‚ is the rotational analog of a rigid body to a linear or an angular motion. It is one of the fundamentals of the dynamics of rotational motion. The moment of inertia must always be in a specified chosen axis of rotation. The point of motion is basically defined as the relationship between mass and the perpendicular distance to the rotational

Newton’s 2nd law of motion: Force produces acceleration in an object in its own direction. The acceleration is directly proportional to the force and inversely proportional of the mass of the object. Resultant force is unbalanced force. F=ma ‚ where F is the resultant force. Q: the mass of a boy n his bicycle is 30kg‚ wants to accelerate at 1.5per sec square if the opposing force is acting on both is 40N Find the force needed for this acceleration. Q2: a car of weight 50‚000N is moving

Angular Kinematics An object on a point that rotate a fixed axis has circular motion around the same axis. Linear quantities cannot be used for circular motion. This is due to the extended objects rotational motion rather that a particles linear motion. Circular motion‚ for this reason‚ is described in terms of the change in angular position. Except for the points on the axis‚ all the points on a rotating rigid object during any time interval move through the same angle. Many equations describing
