Air is a physical substance which has weight. It has molecules which are constantly moving. Air pressure is created by the molecules moving around. Moving air has a force that will lift kites and balloons up and down. Air is a mixture of different gases; oxygen‚ carbon dioxide and nitrogen. All things that fly need air. Air has power to push and pull on the birds‚ balloons‚ kites and planes. In 1640‚ Evangelista Torricelli discovered that air has weight. When experimenting with measuring mercury

the best minds for most of the previous 2000 years. His first law states that every object continues in a state of rest‚ or of uniform speed in a straight line‚ unless acted on by a nonzero net force. This is normally taken as the definition of inertia. The key point here is that if there is no net force resulting from unbalanced forces acting on an object‚ if all the external forces cancel each other out‚ then the object will maintain a constant velocity. If that velocity is zero‚ then the object

Mathematicians and scientists call a quantity which depends on direction a vector quantity‚ and a quantity which does not depend on direction is called a scalar quantity. Vector quantities have two characteristics‚ a magnitude and a direction. Scalar quantities have only a magnitude. When comparing two vector quantities of the same type‚ you have to compare both the magnitude and the direction. For scalars‚ you only have to compare the magnitude. When doing any mathematical operation on a vector

Problem set number 1- Palak Sharma Distance a scalar quantity that refers to “how much ground an object has covered” during its motion. Formulas used: Newtons laws are: (1) Every object moves in a straight line unless acted upon by a force. (2) The acceleration of an object is directly proportional to the net force exerted and inversely proportional to the object’s mass. (3) For every action‚ there is an equal and opposite reaction. Formulas used: F=ma Displacement is a vector quantity that

When the gas rushes out of the balloon’s mouth it moves forward which starts a movement called thrust. Thrust requires both energy and direction. When the air moves out in one direction from the balloon‚ it flies in the opposite direction. This is an example to Newton’s third law of motion‚ "To every action there is an equal opposite reaction." The characteristics to explain that an Action Force results in a Reaction Force are that the two forces should be equal in magnitude. The two forces are in

Aim: a:‚ To observe changes in motion due to changes in force and measure force‚ mass and acceleration‚ and examine their influence on motion. b: To investigate the relationship between the variables; mass‚ force and acceleration and determine an inertial mass through the use of a trolley‚ ticker-timer and set of slotted masses. Introduction: Newton ’s second law states "The acceleration of an object as produced by a net force is directly proportional to the magnitude of the net force‚ in the

For this quarter we started off with a bottle rocket project. This project lead us to become more educated with Newton’s laws of motion. The bottle rockets also lead you to learn about mass‚ force‚ and acceleration. As you know the first law of motion is that if objects at rest will stay at rest‚ or objects in motion will stay in motion‚ unless acted upon by an unbalanced force. Well in order for the rocket to lift off it will need force applied to it. It is required to add water for your rocket
