What is the horizontal acceleration of a projectile as its position changes?
Wiki User
∙ 13y ago
In the usual simple treatment of projectile motion, the horizontal component of
the projectile's velocity is assumed to be constant, and is equal to the magnitude
of the initial (launch) velocity multiplied by the cosine of the elevation angle at the
time of launch.

∙ 13y agoIf you can ignore the effects of air resistance, the horizontal component of
projectile velocity doesn't change at all.
Wiki User
∙ 13y agoThere is no acceleration horizontally, only vertically due to gravity (g=9.81ms^-2)

∙ 12y agoThe vertical component of its velocity will grow at the rate of 9.8 meters (32.2 feet)
per second2 referenced to the downward direction.

What is the rate at which speed or direction changes?
Acceleration
All objects resist changes in?
acceleration.
Acceleration is defined as the rate change of position true or false?
Acceleration (ack-sell-uh-RAY-shun) is can be absolute, angular, and coriolis. All three are accelerations because they change position/speed over time. Velocity is a measure of distance moved over time. Acceleration is velocity that is changing (speeding up or slowing down, or changing direction) Absolute: The speed continually changes. (A car speeding up) Angular: The direction continually changes. (A planet circling the Sun in orbit) Coriolis: A combination of the above, where a particle changes its distance (absolute) to the center of a whirling mass (Angular).
What is the value of acceleration for a body?
Acceleration means how fast the body's velocity changes - in symbols, dv/dt. Average acceleration during a certain time is equal to (change in velocity) / (time elapsed). Since you are dividing a velocity by a time, the standard unit for acceleration is (meters / second) / second, but this is normally written as meters / second squared.
What is the rate at which velocity changes over time called?
Acceleration. Not buttery in the slightest.
Which of the velocity component of projectile changes and other remain constant why?
the horizontal component remain unchanged because there in no acceleration in horizontal direction
What is the trajectory of the projectile?
An "ideal" projectile trajectory ... without the influence of wind or air resistance ... is a section of a parabola. That's the figure you get when the horizontal position changes at constant speed and the vertical position changes at a speed that is itself changing at a constant rate.
What is the shape of a projectile trajectory?
An "ideal" projectile trajectory ... without the influence of wind or air resistance ... is a section of a parabola. That's the figure you get when the horizontal position changes at constant speed and the vertical position changes at a speed that is itself changing at a constant rate.
Why does the horizontal component of velocity for a projectile remain constant while the vertical component changes?
Since the velocity is constant due to the fact that there are no external forces acting in the horizontal direction, if you neglect air resistance, therefore, the horizontal velocity of a projectile is constant.
What are acceleration and velocity?
'Velocity' means the rate at which position changes, and the direction in which it changes. 'Acceleration' means the rate at which velocity changes, and the direction in which it changes.
How does a wheel and axle change distance?
They don't. Distance is the same no matter what. What changes is the ability to convert energy to horizontal acceleration.
Which physical quantity changes continually during a uniform circular path?
The position, the velocity, and the acceleration.
Which velocity component changes along the path?
The motion of a projectile is a combination of two motions, a constant speed motion in the horizontal direction, and an accelerated motion in the vertical direction. The velocity component that changes along the path is Vy.
What kind of form of energy is the change of position?
If the change of position is horizontal, then there's no energy involved. If it's a vertical change, then gravitational potential energy changes.
Why at a constant speed if an object changes its direction it is considered to be acceleration?
Acceleration is a direction plus a speed. If either changes then the acceleration changes.
What is the difference between the utricle and saccule in the ear?
They both provide information about changes in velocity when travelling either horizontally or vertically. However, the utricle is more sensitive to horizontal acceleration , whereas the saccule is more sensitive to vertical acceleration.
What is the rate at which an object velocity changes?
Acceleration
