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.
How do you represent the path of an object in projectile motion?
Important Points of Projectile Motion
The path of a projectile is parabolic. Throughout the motion, the acceleration of projectile is constant and acts vertically downwards being equal to g. The
angular momentum of projectile = mu cos Θ × h
where the value of h denotes the height.
What determines the path that an object in projectile motion follows quizlet?
Which describes an object in projectile motion? … Gravity acts to pull the object down.
The object’s inertia carries it forward
. The path of the object is curved.
Which path is followed by a projectile?
The path followed by a projectile is called
its trajectory
.
Why does an object in projectile motion follow a parabolic path?
Projectile motion is parabolic because
the vertical position of the object is influenced only by a constant acceleration
, (if constant drag etc. is also assumed) and also because horizontal velocity is generally constant.
What determines the path that an object in projectile motion follows ignore air?
A projectile is an object in motion from space that enters the earth’s atmosphere. When it gets to the earth, it is pulled by the force of earth’s gravity. As it enters earth’s atmosphere,
its inertia
determines its path.
Do resting objects have inertia?
Inertia is a force which keeps stationary objects at rest and moving objects in motion at constant velocity. Inertia is a force which brings all objects to a rest position.
All objects have inertia
. A more massive object has more inertia than a less massive object.
What are the 2 types of projectile motion?
Many projectiles not only undergo a vertical motion, but also undergo a horizontal motion. That is, as they move upward or downward they are also moving horizontally. There are the two components of the projectile’s motion –
horizontal and vertical motion
.
What do you call the path taken by an object moving in projectile motion?
Projectile motion is a form of motion where an object moves in parabolic path; the path that the object follows is called
its trajectory
.
Can we predict the motion of a moving object?
Newton’s second law
of motion says that the acceleration of an object is directly proportional to the net force applied to it and inversely proportional to its mass. You can use it to predict the motion of an object. The net force is the vector sum of all the forces that act on the object.
What is nature of path of projectile?
Answer: the nature of path of a projectile is
a parabola ∩
.
What is the path of a projectile quizlet?
The curved flight path a projectile follows is called
a trajectory
and is a parabola. The height, time of flight, initial velocity, and horizontal distance of this path are related by the equations of motion.
Which causes the acceleration of objects on projectile?
A projectile is an object upon which the only force is
gravity
. Gravity acts to influence the vertical motion of the projectile, thus causing a vertical acceleration. The horizontal motion of the projectile is the result of the tendency of any object in motion to remain in motion at constant velocity.
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.
Why is the path of a projectile curved when it is thrown horizontally?
Horizontal component of motion is completely independent of the vertical component of motion. Their combined effects produce the variety of curved paths that projectiles follows. We find that projectiles
move equal horizontal distances in equal time intervals
since no acceleration takes place horizontally.
What is the magnitude and direction of acceleration of a body in projectile motion at the highest point?
At its highest point, the
vertical velocity is zero
. As the object falls toward Earth again, the vertical velocity increases again in magnitude but points in the opposite direction to the initial vertical velocity.
