What happens when a projectile is launched horizontally?

A projectile is launched at an angle to the horizontal and rises upwards to a peak while moving horizontally. Upon reaching the peak, the projectile falls with a motion that is symmetrical to its path upwards to the peak….Check Your Understanding.

Horizontal Info:	Vertical Info:
ax = 0 m/s/s	ay = -9.8 m/s/s

Why do projectiles not accelerate horizontally?

A projectile is any object upon which the only force is gravity, Projectiles travel with a parabolic trajectory due to the influence of gravity, There are no horizontal forces acting upon projectiles and thus no horizontal acceleration, The horizontal motion of a projectile is independent of its vertical motion.

Why does the horizontal component of a projectile remains constant?

The horizontal motion of the projectile is the result of the tendency of any object in motion to remain in motion at constant velocity. Due to the absence of horizontal forces, a projectile remains in motion with a constant horizontal velocity.

What happens to a ball thrown horizontally?

The time required for initially horizontal projectile motion to occur is the same as the time required for the object to fall to its final height. Thus, a ball thrown horizontally will reach the ground at the same time as a ball dropped from the same height.

How does spin affect projectile motion?

The amount and direction of spin acting on a projectile will directly affect the distance a projectile will travel. The reason for this is the air pressure acting on the ball. In a tennis shot, topspin gives poorer distance compared to backspin. Range is decreased with topspin.

What factors affect how far a projectile will land?

Factors affecting the flight path of a Projectile are:

• Gravity.
• Air Resistance.
• Speed of Release.
• Angle of Release.
• Height of Release.
• Spin.

Why does the projectile not matter when there is no air resistance?

In the absence of air resistance there are no forces or components of forces that act horizontally. In the absence of air resistance the only force acting on a projectile in flight is the weight of the object. Weight by definition acts vertically downwards, hence no horizontal component.

What is the acceleration of a projectile in the horizontal direction?

Nothing accelerates a projectile horizontally, so horizontal acceleration is always zero.

Why is the horizontal component of velocity constant in projectile motion?

The velocity of the horizontal component of the projectile motion is constant because there is no external force which acts on the horizontal component of the velocity, but the external force acts on the vertical component of the velocity.

Why does the ball continue horizontally and not just fall vertically?

The factor which leads to the balls falling is the gravity. Because throwing horizontally means it has no vertical component, that is why the vertical motion for both balls are the same. So although the ball with initial horizontal velocity will reach a farther distance, the balls drop at the same time.

What will fall first gravity?

Common Ideas About Falling Heaver objects fall faster. If you drop a heavy and light object together, the heavy one will get to the ground first. This is trick question. I remember in physics that everything falls the same.

What affects 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 a projectile travel with a constant horizontal velocity?

The vertical force acts perpendicular to the horizontal motion and will not affect it since perpendicular components of motion are independent of each other. Thus, the projectile travels with a constant horizontal velocity and a downward vertical acceleration.

What happens to a projectile when the Gravity Switch is off?

The projectile still moves the same horizontal distance in each second of travel as it did when the gravity switch was turned off. The force of gravity is a vertical force and does not affect horizontal motion; perpendicular components of motion are independent of each other.

Do all projectiles have a vertical 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 happens to a particle at rest and in projectile motion?

So if it is at rest then it will remain in rest OR if it was moving with some velocity then it will continue to move forever with that constant velocity. In case of projectile motion the vertical component of particle’s velocity changes continuously because of the force acting in vertical direction which is its own weight ( mg ).
