Is the initial velocity the same as the final velocity?
Final velocity (v) of an object equals initial velocity (u) of that object plus acceleration (a) of the object times the elapsed time (t) from u to v.
Is the initial velocity of an object is equal to final velocity The value of acceleration is?
if Initial velocity of object is equal to final velocity, the value of acceleration is zero.
What is the value of its initial velocity?
Initial Velocity is the velocity at time interval t = 0 and it is represented by u. It is the velocity at which the motion starts.
How do you find the initial velocity of a projectile?
All objects at the beginning of their projectile motion must possess a non-zero initial velocity. The initial velocity can always analysed as and resolved into two components: horizontal and vertical velocities. This is done by constructing a right-angled triangle from vectors.
Does a projectile have a horizontal or vertical component?
If a projectile is launched at an angle to the horizontal, then the initial velocity of the projectile has both a horizontal and a vertical component. The horizontal velocity component ( vx) describes the influence of the velocity in displacing the projectile horizontally.
What is the acceleration of a projectile with no horizontal force?
There are no horizontal forces acting upon projectiles and thus no horizontal acceleration, The horizontal velocity of a projectile is constant (a never changing in value), There is a vertical acceleration caused by gravity; its value is 9.8 m/s/s,…
What are the two key principles of projectile motion?
The numerical information in both the diagram and the table above further illustrate the two key principles of projectile motion – there is a horizontal velocity that is constant and a vertical velocity that changes by 9.8 m/s each second.
