How long does it take for the ball to hit the ground?
three seconds
Does it take a ball longer to go up or down?
While coming down, the force of air drag is upward and the force of gravity is downward, so the ball’s downward acceleration has average magnitude less than g, say adown < g. . As aup > adown, so tdown > tup , thus it takes longer coming down.
At which point is the ball travel slowest?
The speed of the dropped ball increases linearly with time. The ball moves with the slowest speed near the window and with the fastest speed near the point it hits the ground. In half the time it takes to reach the ground it covers less than half the distance and is still above the midpoint between window and ground.
Why a ball thrown up comes down?
This is because the force of earth’s gravitational field is always directed downwards (towards the center of the earth. When the ball is thrown up, it is going against the earth’s gravitational field and so, the earth’s gravitational force pulls it back down, accelerating it downwards.
When we throw a ball upward what happens to its speed?
When we throw a ball upwards, its speed retards gradually. This is because the earth produces a gravitational force which brings down everything that goes up. So when a ball is thrown upward the gravity applies force to bring it down which decreases its speed of going up.
When you throw a ball upward causes the path of the ball to?
When you throw a ball up in the air, its direction/velocity on the way up, although it rises up into the air, is actually downward. On its way up, its speed decreases, until it momentarily stops at the very top of the ball s motion. Its acceleration is -9.8 m/s^2 at the very top.
Why does an object fall?
The force of gravity causes objects to fall toward the center of Earth. The acceleration of free-falling objects is therefore called the acceleration due to gravity. The direction of the acceleration due to gravity is downward (towards the center of Earth).
When you throw a ball upward its kinetic energy?
When you throw a ball upward, its kinetic energy decreases and its potential energy increases. When the ball reaches maximum height, its kinetic energy is at a minimum.
