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.
How many types of projectile motion are there?
In a Projectile Motion, there are two simultaneous independent rectilinear motions: Along the x-axis: uniform velocity, responsible for the horizontal (forward) motion of the particle. Along y-axis: uniform acceleration, responsible for the vertical (downwards) motion of the particle.
What are the 3 types of projectiles?
Three types of projectiles— the bullet, the round ball, and shot—are used in muzzleloaders.
What is a Type 2 projectile?
Type 2 projectile motion. A type 2 projectile motion is where an object is launched with some initial velocity at an angle above the horizontal. Example: θ = angle of launch. Maximum height.
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.
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.
What are the factors affecting motion?
Objects change their motion because unbalanced forces act on them. There are four main factors that affect the motion of objects. These factors are force, friction, inertia, and momentum.
Why does mass not affect projectile motion?
When an object is dropped from a tower, mass does not affect final velocity or time. When writing equations of motion for a dropped object, mass is in the equations in 2 places and they cancel out. That is basically the reason that mass does not affect the results of analysis of a projectile.
Will a heavier ball hit the ground first?
In other words, if two objects are the same size but one is heavier, the heavier one has greater density than the lighter object. Therefore, when both objects are dropped from the same height and at the same time, the heavier object should hit the ground before the lighter one.
Will a bowling ball fall faster than a feather?
Spoiler: the answer is that they will all fall at the exact same rate. Though some objects, like feathers, seem to fall slower because of air resistance.
How fast will a bowling ball fall?
9.8 m/s²
Why did the hammer and feather fall at the same time?
It is because it has a higher surface area to weight ratio, thus is slowed more by drag (or air resistance). On the moon there is no air, and no drag, and a hammer and a feather will fall at the same speed. The earth’s gravity pulls all objects down at the same rate(9.8 m/s 2), assuming there is no air resistance.
Why do balls eventually stop bouncing?
If you drop the basketball, the force of gravity pulls it down, and as the ball falls, its potential energy is converted to kinetic energy. This is because the basketball had an inelastic collision with the ground. After a few bounces, it stops bouncing completely.
What will happen when two balls of the same mass but different volumes are dropped?
Answer. Answer: Gravitational force is equal on all the bodies. Also volume is inversely proportonal to density for constant mass, so the body will experience greater effect of air resistance,this decreases the velocity of fall and prolongs the time required to hit the ground.
What forces eventually cause the ball to stop?
The force in question is friction. There is also friction between the ground and part of the ball that touches the ground as it rolls. The friction force acts in the opposite direction to the motion of the ball, slowing it and eventually stopping it.
Is force necessary to keep the ball rolling Why?
In the absence of any forces, no force is required to keep an object moving. An object (such as a ball) tossed in the earth’s atmosphere slows down because of air resistance (a force).
