The vertical velocity of a projectile changes by
9.8 m/s each second
, The horizontal motion of a projectile is independent of its vertical motion.
How does initial velocity affect projectile motion?
(a) The greater the initial speed v0,
the greater the range for a given initial angle
. (b) The effect of initial angle θ
0
on the range of a projectile with a given initial speed. … If, however, the range is large, the Earth curves away below the projectile and acceleration of gravity changes direction along the path.
How does velocity affect projectile distance?
Speed of release
Speed or velocity is directly related to distance. The greater the speed of release, the greater the distance covered in flight. It is divided into two components: Initial Vertical Velocity.
What are the factors that affect projectile motion?
- Gravity.
- Air Resistance.
- Speed of Release.
- Angle of Release.
- Height of Release.
- Spin.
How does angle and velocity affect projectile motion?
Higher launch angles have
higher maximum height
The maximum height is determined by the initial vertical velocity. Since steeper launch angles have a larger vertical velocity component, increasing the launch angle increases the maximum height.
Is V initial 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.
Can initial velocity be zero?
When a body starts from rest or it changes it direction of motion,it is called as initial velocity. … Generally
at time (t=0),the initial velocity is zero
.
Does the initial velocity affect acceleration?
3.
Initial velocity is independent of the slope
of the graph; that is, the acceleration. An object thrown downward still accelerates after release at the same rate as an object that is dropped.
What is the velocity at the highest point?
At a projectile’s highest point, its
velocity is zero
. At a projectile’s highest point, its acceleration is zero.
Why is 45 degrees the best angle for projectile motion?
The sine function reaches its largest output value, 1
, with an input angle of 90 degrees, so we can see that for the longest-range punts 2θ = 90 degrees and, therefore, θ = 45 degrees. A projectile, in other words, travels the farthest when it is launched at an angle of 45 degrees.
What is the most important factor in projectile motion?
There are 3 factors that are most important in projectile motion:
The projection angle
.
The magnitude of projectile velocity
.
The height of the projection
.
What are the limitations of projectile motion?
– In the projectile motion
the air resistance is neglected at several instants during the motion
. – Projectile motion will only take place until and unless it has the energy preserved in it but as soon it runs out of energy then further no projectile motion will take place in the object.
What kind of motion is the horizontal motion of a projectile?
| Time Horizontal Velocity Vertical Velocity | 5 s 20 m/s, right 49.0 m/s, down |
|---|
What are the major components of a projectile motion?
There are the two components of the projectile’s motion –
horizontal and vertical motion
. And since perpendicular components of motion are independent of each other, these two components of motion can (and must) be discussed separately.
What is the formula of range in projectile motion?
Range. The range of the motion is fixed by the condition y=0 . Using this we can rearrange the parabolic motion equation to find the range of the motion:
R=u2⋅sin2θg R = u 2 ⋅ sin 2 θ g .
