What is meant by components of velocity?
Determining the Components of a Velocity Vector The two parts of a vector are known as components and describe the influence of that vector in a single direction. If a projectile is launched at an angle to the horizontal, then the initial velocity of the projectile has both a horizontal and a vertical component.
What is meant by components of a vector?
Each part of a two-dimensional vector is known as a component. The components of a vector depict the influence of that vector in a given direction. The combined influence of the two components is equivalent to the influence of the single two-dimensional vector.
What are the two components of a force?
The components of a force represent the combined vertical and horizontal forces that combine to make the resultant force. I want to talk about components of a vector. Components are two vectors that add up to the given vector which are perpendicular to each other so let’s start with an example.
What are the two components of a vector quantity?
A vector quantity has two characteristics, a magnitude and a direction. When comparing two vector quantities of the same type, you have to compare both the magnitude and the direction. On this slide we describe a mathematical concept which is unique to vectors; vector components.
What are horizontal and vertical components of force?
The vertical component describes the upward influence of the force upon Fido and the horizontal component describes the rightward influence of the force upon Fido.
How do you resolve vectors to horizontal and vertical components?
Any vector can be resolved into a horizontal and a vertical component. If →R is a vector, then the horizontal component of →R is →Rx and the vertical component is →Ry. When resolving into components that are parallel to the x- and y-axes we are always dealing with a right-angled triangle.
Which factor is most important in projectile motion?
FACTORS AFFECTING PROJECTILE MOTION There are three main factors that affect the trajectory of an object or body in flight: the projection angle, magnitude of projection velocity and height of projection.
Why does the vertical component of velocity for a projectile change with time whereas the horizontal component of velocity does not?
The vertical component changes because vertical motion is influenced by the gravitational force (which acts in the vertical direction). The horizontal component of velocity doesn’t change because there is no component of gravitational force acting horizontally.
What is the horizontal component of the velocity just before it hits answer in units of M S?
Therefore the horizontal component of velocity will be 35 m/s.
What is acceleration and velocity at maximum height?
At a projectile’s highest point, its velocity is zero. At a projectile’s highest point, its acceleration is zero.
Why is acceleration zero at maximum height?
The instantaneous speed of any projectile at its maximum height is zero. Because gravity provides the same acceleration to the ball on the way up (slowing it down) as on the way down (speeding it up), the time to reach maximum altitude is the same as the time to return to its launch position.
What is the velocity vector at the maximum height?
The maximum height of the projectile is when the projectile reaches zero vertical velocity. From this point the vertical component of the velocity vector will point downwards. The horizontal displacement of the projectile is called the range of the projectile and depends on the initial velocity of the object.
