What is meant by the critical velocity of a ball moving in a vertical circle?
The critical velocity of a ball moving in a vertical circle is the minimum velocity required at the top of the circle to prevent the ball from losing contact with the track. Below the critical velocity, the ball will fall off the track at the top of the circle.
What is the horizontal component of the initial velocity of the ball?
The horizontal component of the initial velocity of the ball is the velocity in the horizontal direction at the moment the ball is launched. It represents the speed and direction at which the ball is moving side-to-side.
A boy catches a ball while standing on roller skates What happens to the boy's velocity and the ball's velocity?
The ball's velocity changes to 0m/s and the boy's stays the same.
How can the horizontal distance traveled by the ball increase?
The horizontal distance traveled by the ball can increase by increasing the initial velocity of the ball or by reducing the effect of air resistance. Additionally, increasing the launch angle of the ball can also help it travel further horizontally.
What is the velocity of a ball thrown upward at 16 feetsec?
The velocity of the ball is 16 feet/sec when it is thrown upward.
What effect does the force of gravity have on the ball thrown upwards?
The ball returns to the ground with increasing velocity due to acceleration due to gravity. At a point (terminal velocity) the ball maintains a constant velocity (due to air resistance) This occurs when the weight of the ball is equal to the viscous drag of the air (air resistance) and upthrust (weight of air displaced).
What is meant by the critical velocity of a ball moving in a vertical circle?
The critical velocity of a ball moving in a vertical circle is the minimum velocity required at the top of the circle to prevent the ball from losing contact with the track. Below the critical velocity, the ball will fall off the track at the top of the circle.
You throw a ball straight up with a velocity of 40 meters per second. What is the ball's velocity after 3 seconds?
You throw a ball straight up with a velocity of 40 meters per second. What is the ball's velocity after 3 seconds?
How does mass effect velocity?
It doesn't. But velocity does effect mass : as velocity increases, mass increases.
What is the horizontal component of the initial velocity of the ball?
The horizontal component of the initial velocity of the ball is the velocity in the horizontal direction at the moment the ball is launched. It represents the speed and direction at which the ball is moving side-to-side.

Which ball has more velocity on grass?
a cricket ball
How can the horizontal distance traveled by the ball increase?

What is the velocity of a ball thrown upward at 16 feetsec?
The velocity of the ball is 16 feet/sec when it is thrown upward.
You throw a ball straight up with a velocity of 40 meters per second. What is the ball's velocity after 5 seconds?
The velocity of the ball will be -30 m/s (downward) after 5 seconds due to gravity.
What is the acceleration of the ball during any of these time intervals and at the moment the ball has zero velocity?
The acceleration of the ball is constant during any time interval where the velocity changes. At the moment the ball has zero velocity, the acceleration is the same as it was during the time interval when the velocity was changing. This can be calculated using the formula acceleration = change in velocity / change in time.
While in empty space an astronaut throws a ball at a velocity of 14 ms. What will the velocity of the ball be after it has traveled 2 meters?
The velocity of the ball will remain constant at 14 m/s since there are no external forces acting on it to change its velocity in empty space.
