Why does an object thrown vertically upward always fall with the same velocity?
The instantaneous speed of any projectile at its maximum height is zero. Because gravity provides the same acceleration to the ball on the way up (slowing it down) as on the way down (speeding it up), the time to reach maximum altitude is the same as the time to return to its launch position.
When an object is thrown vertically upwards at the highest point the body acceleration is equal to?
So, even at the highest point, the acceleration will be 9.8 m/s².
What happens when a ball is thrown vertically upwards?
When the body is thrown upwards, it moves up until the velocity of the ball becomes zero and the force exerted on it becomes zero. After that the ball reaches the ground with the acceleration due to gravity with the zero velocity. When the ball goes up, the height of the ball increases and it also moves up.
When a body is thrown vertically upwards What is its acceleration?
When a body is thrown vertically upwards, its velocity is decreasing so the acceleration due to gravity (g) is taken as negative i.e. g = – 9.8 ms–2. When a body is dropped freely from a height, its initial velocity (u) is zero. When a body is thrown vertically upwards, its final velocity (v) becomes zero.
What is the momentum at the highest point of a ball thrown vertically upwards?
Momentum = Mass × Velocity Hence, momentum is zero.
What an object is thrown vertically upward is is accelerating?
Acceleration due to Gravity: When an object is thrown upwards, it returns back to the ground. This acceleration that is experienced by a falling object is known as the acceleration due to gravity. The acceleration due to gravity is caused by the gravitational force acting on the object and hence the name.
What is the initial velocity of the ball thrown vertically upwards?
A ball is thrown vertically upwards with a velocity of 49 m/s. Calculate (1) The maximum height to which it rises. (2) The total time it takes to return to the surface of the earth. Initial velocity of the ball (u) = 49m/s.
How do you calculate the velocity of a body thrown up?
The velocity u with which it is thrown up= +50 m/s, and the acceleration due to gravity g= -10 m/s². Using the relation, 0 = 50 t – ½ × 10 × t²; ==> 50 = 5t , or t = 10s. The body shall return after 10s after being thrown up.
Why does an object thrown upwards come down after reaching a point?
Why an object thrown upwards comes down after reaching a point? When an object is thrown with certain initial velocity (say V), it gains a Kinetic energy at that moment of throwing. As it moves upwards from its initial position (wherefrom it’s thrown) and gains height, its potential energy rises.
What happens to kinetic energy when an object is thrown?
When an object is thrown with certain initial velocity (say V), it gains a Kinetic energy at that moment of throwing. As it moves upwards from its initial position (wherefrom it’s thrown) and gains height, its potential energy rises. This happens because Potential Energy (PE) is directly proportional to the height of the object.
