**__Four Forces:__** Taylor Massa 1. <span style="color: windowtext; font-family: 'Arial','sans-serif'; font-size: 10pt; line-height: 115%; text-decoration: none;">[|weight] · <span style="font-family: 'Arial','sans-serif'; font-size: 10pt; line-height: 115%;">The magnitude of the weight [|depends] on the mass of all of the parts of the rocket. The weight force is always directed towards the center of the earth and acts through the [|center of gravity]. · <span style="font-family: 'Arial','sans-serif'; font-size: 10pt; line-height: 115%;">Some full scale rockets can move, or [|gimbal], their nozzles to produce a force which is not aligned with the center of gravity. The resulting [|torque] about the center of gravity can be used to maneuver the rocket.

2. <span style="color: windowtext; font-family: 'Arial','sans-serif'; font-size: 10pt; line-height: 115%; text-decoration: none;">[|thrust] · <span style="font-family: 'Arial','sans-serif'; font-size: 10pt; line-height: 115%;">The magnitude of the thrust [|depends] on the mass flow rate through the engine and the velocity and pressure at the exit of the nozzle. The thrust force normally acts along the longitudinal axis of the rocket and therefore acts through the center of gravity. 3. <span style="font-family: 'Arial','sans-serif'; font-size: 10pt; line-height: 115%;">aerodynamic forces (lift and drag)

· <span style="font-family: 'Arial','sans-serif'; font-size: 10pt; line-height: 115%;">The magnitude of the aerodynamic forces [|depends] on the shape, size, and velocity of the rocket and on [|properties] of the atmosphere. The aerodynamic forces act through the [|center of pressure]. · <span style="font-family: 'Arial','sans-serif'; font-size: 10pt; line-height: 115%;">Aerodynamic forces are very important for model rockets, but may not be as important for [|full scale] rockets.

**__ Laws Of Motions __**

• Newton's first law states that every object remains at rest or in uniform motion in a straight line unless compelled to change its state by the action of an external force. • The second law explains how the velocity of an object changes when it is subjected to an external force. • The third law states that for every action (force) in nature there is an equal and opposite re-action.

Aerodynamics is the study of forces and the resulting motion of objects through the air.

__**Newton's Laws of Gravity**__

First Law: states that every object will remain at rest or in uniform motion in a straight line unless compelled to change its state by the action of an external force Pasted from <[]> [] Second Law: explains how the velocity of an object changes when it is subjected to an external force. The law defines a **force** to be equal to change in **momentum** (mass times velocity) per change in time Pasted from <[]> [] Third Law: states that for every action (force) in nature there is an equal and opposite reaction Pasted from <[]> []

Morgan ==== Bottle rockets are excellent devices for investigating Newton's Three Laws of Motion. The rocket will remain on the launch pad until an unbalanced force is exerted propelling the rocket upward (First Law). The amount of force depends upon how much air you pumped inside the rocket (Second Law). You can increase the force further by adding a small amount of water to the rocket. This increases the mass the rocket expels by the air pressure. Finally, the action force of the air (and water) as it rushes out the nozzle creates an equal and opposite reaction force propelling the rocket upward (Third Law). ====

<span style="font-family: Tahoma,Geneva,sans-serif; font-size: 120%;">Myia <span style="font-family: Tahoma,Geneva,sans-serif; font-size: 120%;">A rocket or rocket vehicle is a missile, spacecraft, aircraft or other vehicle which obtains thrust from a rocket engine. In all rockets, the exhaust is formed entirely from propellants carried within the rocket before use. Rocket engines work by action and reaction. Rocket engines push rockets forwards simply by throwing their exhaust backwards extremely fast.

There is a toy in Japan that uses the Newton's first law!!!!!
