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
How is the horizontal component of velocity for a projectile affected by the vertical component?
The horizontal component of velocity for a projectile is not affected by the vertical component at all. Horizontal component is measured as xcos(theta) Vertical component is measured as xsin(theta) Whereas theta is the angle, and x is the magnitude, or initial speed.
A bullet fired horizontally over level ground hits the ground in 0.5 seconds If it had been fired with twice the speed in the same direction it would have hit the ground when?
Assuming no affects from air and a smooth geography, both bullets would fall at the same rate of 9.81 m/s^2 toward earth, and hit the ground simultaneously. You have to look at the bullet's velocity as having a horizontal and vertical velocity vectors. The vertical velocity vector is independent from that of the horizontal. The horizontal vector would be the speed at which the bullet is fired, and the vertical vector is the speed at which the bullet falls due to gravity.
When during a jump is your speed zero?
Your vertical speed is zero when you're at the highest point of your jump. After that, itbegins to grow again, but in the downward direction. Your vertical speed is the samewhen you hit the ground as it was when you left the ground, but in the opposite direction.Your horizontal speed doesn't change. It's the same when you hit the ground as it waswhen you left the ground, and in the same direction.
Why throwing a ball always put down in curve not in straight?
-- The only horizontal force on a thrown ball is the force of air resistance, so the horizontal acceleration is very small, and the horizontal speed stays almost constant. -- The vertical force on a thrown ball is the force of gravity, so the ball accelerates straight down at the acceleration of gravity. -- The result of unequal horizontal and vertical components of acceleration is a curved path.
Is the line perfectly vertical on a speed graph if you were standing still?
No. If the horizontal axis is time, and the vertical axis is speed, and you're standing still,Then the graph is perfectly horizontal, and it coincides with the horizontal axis.
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
If a gragh shows time on the horizontal axis and speed on the vertical axis a straight horizontal line across the gragh would indicate what?
A constant speed.
If a graph shows time on the horizontal axis and speed on the vertical axis a straight horizontal line across the graph would indicate?
constant speed
What kind of graph shows time on the horizontal axis and speed on the vertical axis a straight horizontal line?
Acceleration
A graph has time on the horizontal axis and speed on the vertical axis a straight horizontal line across the graph would indicate what?
The given speed is constant for the given period
In a graph showing time on the horizontal axis and speed on the vertical axis What would a straight horizontal line indicate?
The line would indicate motion at a constant speed.
If a graph shows time on the horizontal axis and speed on a vertical axis a straight horizontal line across the graph would indicate?
Constant speed ... zero acceleration.
A graph shows distance on the vertical axis and time on the horizontal axisif the speed is steadily increasing what will the line representing speed look like on the graph?
If a graph shows distance on the vertical axis and time on the horizontal axis, and the speed is steadily increasing, the line representing speed will be a straight line.
How is the horizontal component of velocity for a projectile affected by the vertical component?
The horizontal component of velocity for a projectile is not affected by the vertical component at all. Horizontal component is measured as xcos(theta) Vertical component is measured as xsin(theta) Whereas theta is the angle, and x is the magnitude, or initial speed.
What is the steepness of a line graph equal to its vertical change divided by its horizontal change is referred to as the?
Speed
What is the horizontal or vertical number line on a coordinate plane?
They are the axes. Usually horizontal = x-axis, vertical = y-axis. But that need not always apply. In a displacement-time or speed-time graph, for example, the horizontal axis = t-axis (for time).
