What do you mean by trajectory in physics?
A trajectory or flight path is the path that an object with mass in motion follows through space as a function of time. The mass might be a projectile or a satellite. For example, it can be an orbit — the path of a planet, asteroid, or comet as it travels around a central mass.
What is the formula for trajectory?
Trajectory formula y = h + Vy * t – g * t² / 2.
How is trajectory affected by gravity?
Gravity causes a vertical acceleration. The ball will drop vertically below its otherwise straight-line, inertial path. Gravity is the downward force upon a projectile that influences its vertical motion and causes the parabolic trajectory that is characteristic of projectiles.
What does trajectory equation mean?
The trajectory formula helps us to find the gravity that acted on an object. Also, the trajectory has vertical (y) and horizontal (x) position components. Moreover, if we launch the projectile with an initial velocity v_{0}, at an angle \theta from the horizontal plane.
What trajectory means?
1 : the curve that a body (such as a planet or comet in its orbit or a rocket) describes in space. 2 : a path, progression, or line of development resembling a physical trajectory an upward career trajectory.
What does trajectory mean example?
The definition of a trajectory is the curved path something takes as it moves through space. An example of trajectory is the path taken by a paper airplane as it flies through the air.
What is trajectory in physics class 11?
When any object is thrown from horizontal at an angle θ except 90°, then the path followed by it is called trajectory, the object is called projectile and its motion is called projectile motion.
What’s an example of trajectory?
An example of trajectory is the path taken by a paper airplane as it flies through the air. The curved path of something hurtling through space, esp. that of a projectile from the time it leaves the muzzle of the gun.
When a body is projected in a gravitational field?
When a body is projected at an angle with the horizontal in the uniform gravitational field of the earth, the angular momentum of the body about the point of projection, as it proceeds along its path. initially decreases and after its highest point increases.
How do you describe the trajectory of a projectile?
Projectile motion is a form of motion where an object moves in a parabolic path. The path followed by the object is called its trajectory. The angle at which the object is launched dictates the range, height, and time of flight the object will experience while in projectile motion.
What does trajectory mean in history?
refers to the changes undergone by an industrial/commercial/military site over a given period of time (e.g. since the beginning of industrialization) before and after it has become a brownfield. These changes can be conceptualized as more or less distinct stages, separated by turning points.
What does trajectory mean definition?
What is the definition of density in physics?
What is Density – Physics – Definition. What is density. In words, the density (ρ) of a substance is the total mass (m) of that substance divided by the total volume (V) occupied by that substance. Thermal Engineering.
Which is the best description of the trajectory of an object?
Physics of trajectories. One of the remarkable achievements of Newtonian mechanics was the derivation of the laws of Kepler. In the gravitational field of a point mass or a spherically-symmetrical extended mass (such as the Sun ), the trajectory of a moving object is a conic section, usually an ellipse or a hyperbola.
How is the trajectory of an element calculated?
In discrete mathematics, a trajectory is a sequence ( f k ( x ) ) k ∈ N {displaystyle (f^{k}(x))_{kin mathbb {N} }} of values calculated by the iterated application of a mapping f {displaystyle f} to an element x {displaystyle x} of its source.
What is the definition of density in thermal engineering?
Thermal Engineering Typical densities of various substances at atmospheric pressure. Density is defined as the mass per unit volume. It is an intensive property, which is mathematically defined as mass divided by volume:
