Newton's Laws Of Motion

This is accomplished with a motor-driven propeller or a jet engine. When the airplane is in level flight at a constant speed, the force of the thrust is just enough to counteract the aerodynamic drag. Moving air can also generate forces in a different direction from the flow. The force that keeps an airplane from falling is called lift. Lift is generated by an aircraft wing.

When the rocket was first launched, Newton’s third law took effect. The law states that “every action has an equal and opposite reaction”. Burning fuel caused the rocket to move upward, giving the rocket an equal and opposite reaction. The second law has to do with the mass of the rocket. The more weight an object has, the more force is needed to move it.

II. THEORETICAL BACKGROUND A. The Magnitude and Direction of Centripetal Acceleration It has been established that the direction of the centripetal acceleration is always towards the center of the circular path. This way the acceleration is entirely perpendicular to the velocity vector. (If it had a parallel component, then there would be a change in speed, which is no longer centripetal acceleration.)

Moreover, if there were no air resistance, then the skydivers would continue accelerating until they hit the ground. For objects falling through the air, the formula is represented as: psgV – pagV – FD = psVa Where: ps =The density of the falling object pa = The density of the air it’s falling in FD = The drag force g = The gravitational force V = The volume of the falling object. a = The acceleration of the falling

So in theory to steer, it requires a change of direction in both the velocity and acceleration. An airplane steers while it is in the air via a system of flaps on the wings, called control surfaces. Depending on how the flaps are oriented, this determines the direction that the plane will travel. For example, when the pilot wants to turn the plane to the left, he will activate a control surface on the left wing and point the flap downward. This will increase the drag on the left wing while the right wing stays the same, therefore causing the plane to turn left.

How these are all connected? To start with, we should make sense of what these words mean. Gravity: the power that makes something tumble to the ground (at 9.8 m/s²) Newton 's Laws of Motion: three laws that state mechanics portraying the movement of a body. The main law is the law of latency: a body stays very still unless followed up on by an outer power. The second law expresses that a body in movement stays in movement unless followed up on by an outside power.

It states that the acceleration of an object depends on the mass, magnitude, and the forces acting on it. This law sets when the cart is going down hills. The mass is the mass of the cart and passengers, whereas gravity serves as the force acting on it. The passengers are able to feel the force, this changes as the acceleration starts to slow down. The cart starts to slow down because of the friction.

The pipe is in the form of a venturi it narrows in section and then widens again, causing the airflow to increase in speed in the narrowest part. Below the venturi is a butterfly valve called the throttle valve a rotating disc that can be turned end-on to the airflow, so as to hardly restrict the flow at all, or can be rotated so that it (almost) completely blocks the flow of air. This valve controls the flow of air through the carburetor throat and thus the quantity of air/fuel mixture the system will deliver, thereby regulating engine power and speed. The throttle is connected, usually through a cable or a mechanical linkage of rods and joints or rarely by pneumatic link, to the accelerator pedal on a car or the equivalent control on other vehicles or

Force is defined as push or pull interactions between two objects. Weight is the force a person exerted on an object below him/her. Mass is the measurement of how resistant an object is to being accelerated. Newton’s first law of motion states that an object in motion will stay in motion and an object at rest will stay in rest unless a net external force acts upon it. This law means that an object moving at a certain velocity will maintain that same velocity unless an outside acts upon it.

The general theory of relativity is nothing but it is the Einstein's theory of gravity. It is based on two fundamental principles: The principle of relativity which states that all the systems of reference are equivalent with respect to the formulation of the fundamental laws of physics. The principles of equivalence, these principles of equivalence are divided into two categories the weak one which states that the local effects of motion in a curved space (gravity provides a curved space according to the general theory of relativity) are not different from those of an accelerated observer in at space. And the strong one states that the consequence of any local experiment (whether it is a gravitational or not) in a freely falling laboratory
