What will be the nature of velocity when a body is thrown vertically upward?
When an object is thrown vertically upwards the velocity of the object starts to deaccelerate gradually due to the gravitational force acting upon the object which tends to pull down the object towards the earth.
What is the velocity of the vertically thrown upward object at the highest point?
Here, t is the time. Here, v is the final velocity, u is the initial velocity, g is the acceleration due to gravity and h is the height attained by the object. We know that at the maximum height, the velocity of the object becomes zero.
How velocity of a vertically thrown ball varies with time?
The correct answer is Upwards positive. The velocity of a vertically thrown ball, with time, will be “up” in the positive direction. Gravity pulls the ball down, and since that is the only force acting on the ball, neglecting air resistance, the acceleration is always 9.8 m/s2 down or -9.8 m/s2.
What is meant by velocity time graph?
A velocity-time graph shows the speed and direction an object travels over a specific period of time. Velocity-time graphs are also called speed-time graphs. The vertical axis of a velocity-time graph is the velocity of the object. The horizontal axis is the time from the start.
Which of the following graph represents the motion of a ball when thrown upward * 1 point?
When a ball is thrown upwards, it has a constant negative acceleration of g. since slope is constant and negative throughout, graph D is correct.
How do you find the velocity of an object thrown upwards?
When you project an object upward and release it at its initial velocity, it is moving in the opposite direction of the force of gravity….Solution.
| t = 0 s | v = −19.6 m/s | Moving upward from starting point |
|---|---|---|
| t = 1 s | v = −9.8 m/s | Object moving upward |
| tm = 2 s | v = 0 m/s | At peak or maximum displacement |
When a ball is thrown vertically upwards the maximum height?
Hint: When a ball is thrown upwards with a certain velocity, the ball moves against the acceleration due to gravity and attains a maximum height. At the point of maximum height, the velocity of the ball is zero.
