Ignoring air resistance what is the horizontal component of a projectile's acceleration?
Zero.
For motion along a straight line a horizontal line on a speed over time graph indicates graph indicates that what is zero?
For motion at constant speed along a straight line, the acceleration is zero.
An object with a constant acceleration but with zero velocity what is mean is n't possible.?
Yes, it can happen. when the velocity is momentarily zero while an object is changing from moving in the positive direction motion to the negative direction; the object obviously will stop at one point, but will still have a constant acceleration.
Why does the acceleration of an object rolled down an incline increase as the angle of incline increases?
The contribution of the acceleration of gravity in the direction of motion increases as the angle of the incline increases. Or in other words, as the angle between the direction of motion and the force of gravity goes to zero, the acceleration of the object goes to the gravitational acceleration. a = g cos(theta) Where theta is the angle between the direction of motion and verticle, which is in fact (theta = 90 - angle of the incline)Where a is the acceleration of the object down the incline plane and g is the acceleration due to gravity. Theta is the angle between the direction of motion of the accelerating object and the acceleration of gravity. Initially, the angle between a and g is 90 degrees (no incline) and therefore g contributes nothing to the objects acceleration. a = g cos(90) = 0 As the angle of the inclined is increased, the angle between a and g approaches zero, at which point a = g. With no other forces acting upon the object, g is its maximum acceleration.
What is your acceleration if you have a constant velocity?
If your velocity is constant, then your acceleration is zero.
What is the vertical acceleration of a projectile if the vertical component of its velocity vector is zero?
The vertical component of a projectile's velocity is irrelevant. It can be up, down, or zero, makes no difference. As long as projectile motion lasts ... gravity is the only force on the object and you're ignoring air resistance ... its acceleration is constant, and is equal to the acceleration of gravity: 9.8 meters per second2 pointing down.
How do the horizontal components of a projectile motion vary from the vertical components?
Horizontal . . . acceleration is zero, speed is constant Vertical . . . acceleration is 'G' downward, speed constantly increases downward
Is it true to say that a projectile has zero acceleration at its peak. If yes explain if not give a reason?
Yes, it is true to say that a projectile has zero acceleration at its peak.Because the highest height, which the object will reach is known as the peak of the object's motion. The increase of the height will last, until vy = 0.,For more Explanation:Atlas_gondal@yahoo.com
Ignoring air resistance what is the horizontal component of a projectile's acceleration?
Zero.
How is velocity of zero different from an accerlation at zero?
Acceleration is changing velocity. Zero velocity means no motion. Zero acceleration means constant, unchanging motion.
What is net acceleration in a non uniform motion?
For uniform motion, the acceleration is zero. For non-uniform motion, the acceleration is something different than zero - at least, most of the time.
What is the net acceleration in a non uniform motion?
For uniform motion, the acceleration is zero. For non-uniform motion, the acceleration is something different than zero - at least, most of the time.
What is the acceleration of a projectile when instantaneous vertical velocity is zero at the top of its projectile?
Acceleration at the point of zero vertical velocity will be equivalent to gravitational acceleration on that body. On Earth, for example, this is around 9.8 meters per second per second (9.8m/s2).
What is the acceleration in uniform motion?
zero
Can an object be moving if acceleration is zero?
Yes. Acceleration is defined as a change of speed and/or direction of motion. If the speed and direction of motion are constant, then there is no acceleration.
What is the acceleration of uniform motion?
Uniform motion means "constant speed in a straight line".That's another way of saying "zero acceleration".
Can a body moving with constant speed has acceleration?
Yes. Eg : in case of a uniform circular motion. In general, for every motion in which direction of motion of particle keeps changing continuously and the particle moves with same speed, then the net acceleration is non-zero, although tangential acceleration is zero.
