Gravity acts to pull the object down. The object moves in a straight path . The forward velocity of the object is 0 m/s. The object’s inertia carries it forward.
What are the 3 main concepts of projectile motion?
Key Points: Range, Symmetry, Maximum Height . Projectile motion is a form of motion where an object moves in parabolic path. The path that the object follows is called its trajectory.
What describes a object in projectile motion?
A projectile is any object that once projected or dropped continues in motion by its own inertia and is influenced only by the downward force of gravity. By definition, a projectile has a single force that acts upon it – the force of gravity.
Which describes an object in projectile motion gravity acts to push?
Description of an object in projectile motion is; Gravity acts to pull the object down . The object’s inertia carries it forward. The path of the object is curved.
What are the major components of a projectile motion?
There are the two components of the projectile’s motion – horizontal and vertical motion . And since perpendicular components of motion are independent of each other, these two components of motion can (and must) be discussed separately.
What are the example of projectile motion?
Tossing an object into the bin, water flowing from a tap, jumping from a bus, etc are all common examples of projectile motion which we encounter every day. Yes, well-known examples of projectile motion like bullets, slingshots, baseball, rockets are not very common in our daily lives.
What is the principle of projectile motion?
The force of gravity acts on the object to stop its upward movement and pull it back to earth , limiting the vertical component of the projectile. As a projectile moves through the air it is slowed down by air resistance. Air resistance will decrease the horizontal component of a projectile.
How is projectile motion used in real life?
In real life, the projectile motion finds applications in sports . Playing basketball, football is examples of projectile motion in real life. While throwing a basketball into the basket, the player shoots the ball in such a way that the flight taken by the ball is in the form of a parabola.
What are the two components of projectile motion?
Since vertical and horizontal motions are independent, we can analyze them separately, along perpendicular axes. To do this, we separate projectile motion into the two components of its motion, one along the horizontal axis and the other along the vertical.
What determines the path that an object is projectile motion follows?
A projectile is an object in motion from space that enters the earth’s atmosphere. As it enters earth’s atmosphere, its inertia determines its path. The mass of the object determines its inertia. The more mass it has the higher its inertia which causes it to have a longer curvature when pulled by earth’s gravity.
What is the path of a projectile?
Projectile motion is a form of motion where an object moves in a bilaterally symmetrical, parabolic path. The path that the object follows is called its trajectory .
Which change will always result in an increase?
Answer: A change that will always result in an increase in the gravitational force between two objects is: Increase in the mass of the objects and decrease in the distance between them .
What are the factors that may affect the motion of a projectile?
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 .
What is the formula for horizontal projectile motion?
Horizontal projectile motion equations
Horizontal distance can be expressed as x = V * t . Vertical distance from the ground is described by the formula y = – g * t2 / 2 , where g is the gravity acceleration and h is an elevation.
What are the equations for projectile motion?
h = v 0 y 2 2 g . This equation defines the maximum height of a projectile above its launch position and it depends only on the vertical component of the initial velocity.
What are 5 examples of projectile motion?
