This is Expert Verified Answer 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.

## How do you find the height of a ball thrown straight up?

Use the vertical motion model, h = -16t2 + vt + s where v is the initial velocity in feet/second and s is the height in feet, to calculate the maximum height of the ball.

## When a ball is thrown straight up the acceleration is upward?

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.

## What is the velocity of a ball thrown straight up?

A ball is thrown straight up. What is its velocity and acceleration at the top? UPLOAD PHOTO AND GET THE ANSWER NOW! Solution : Velocity is zero and acceleration is `9.8m//s^(2)` in the downward direction.

## When the ball is in upward motion then it is an example of?

ball thrown upward at any angle follows parabolic path. parabola is curve so the motion followed is curvilinear motion.

## What happens to acceleration when object is thrown upward?

When you throw a ball up in the air, its speed decreases, until it momentarily stops at the very top of the ball’s motion. Its acceleration is −9.8 ms−2 at the very top since the body is moving upward against the gravity. In other words, the acceleration due to gravity g=9.8 ms−2↓.

## When a ball is thrown vertically upwards at 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.

## What is the acceleration of the ball that is thrown vertically upward just before it hits the ground?

As said earlier, the acceleration of the ball throughout its motion will be due to gravity ie a=g=9.8 m/s2. a = g = 9.8 m / s 2 . , which is equal to the acceleration of the ball just before it hits the ground.

## What is the maximum height reached by an object that is thrown vertically up with a velocity of UM s?

Therefore, the maximum height reached = 2gu.

## When an object that is thrown straight upward reaches its highest point?

Answer and Explanation: When an object is thrown vertically upward, its velocity decreases at a rate equal to the acceleration due to the earth’s gravity. The upward velocity gets reduced to zero momentarily and the object attains its highest position at that moment.

## When an object is thrown vertically upwards what is its velocity at the highest point?

When a body is thrown vertically upwards, at the highest point only velocity is zero because the acceleration due to gravitational force is acting downward continuously and that is the reason for velocity being zero at the highest point, hence velocity is zero because of the acceleration.

## Why is acceleration negative when a ball is thrown up?

The acceleration due to gravity is downwards towards the surface of the earth. Hence in this case the downward is considered as positive and the upward is considered as negative. Since the acceleration moves the ball up against the force of gravity, it is negative.

## When a ball thrown straight upwards reaches the very top of its path its acceleration is group of answer choices?

Detailed Solution When an object thrown straight upwards gets to the top of its path, Its velocity is zero because it moves opposite to gravity and acceleration is 10 m/s2 , due to the rate of change of velocity of an object with respect to time.

## When a ball is thrown vertically upwards the gravitational potential energy of the ball?

EXPLANATION: When a ball is thrown vertically upwards, the kinetic energy of the ball converted into potential energy of the ball. But the total energy of the ball remains constant during its motion. So option 1 is correct.

## What happened to the object after it was thrown upward?

When you throw an object upwards, it will eventually fall back to the ground under the earth’s gravity. In fact all objects near the earth’s surface fall with a constant acceleration of about 9.8 (we usually take 10 for the sake of simplicity in calculation).

## When a ball is thrown upwards from the earth surface it returns back towards the earth surface Why?

Whenever we throw any object in upward direction, the gravitational pull acts on the body which is in downward direction. Hence it falls back to the ground under the action of Earth’s gravity. Objects falling down under the influence of gravity, fall with a constant acceleration of 9.8 m/s².

## When you throw an object vertically upwards what is direction of acceleration due to gravity during its upward and downward journey?

So, if an object is moving vertically upwards, the direction of motion is positive for upwards journey. Hence, the acceleration due to gravity is taken as negative as its direction is downward. Was this answer helpful?

## Is the acceleration positive or negative when thrown upward?

So, if an object is moving vertically upwards, the direction of motion is positive for upwards journey. Hence, the acceleration due to gravity is taken as negative as its direction is downward.

## When an object is thrown vertically upward why does its speed decreases?

Gravitational pull of earth on the ball – acceleration due to gravity tends to decrease the speed during upward motion and increase the speed during downward motion.

## When a ball is thrown up vertically with velocity?

Q. When a ball is thrown vertically upwards with velocity v0, it reaches a maximum height of h. If one wishes to triple the maximum height then the ball should be thrown with velocity.

## When a ball is thrown upwards it returns to the ground after reaching its maximum height at maximum height it has?

At maximum height its velocity is zero and the acceleration on it, is the acceleration due to gravity which is a constant quantity.

## How the velocity of a vertically thrown ball varies with time velocity is upward positive?

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 the equation of motion for a body thrown vertically upwards?

A body is thrown vertically upward with velocity u, the greatest height h up to which it will rise is h=u22g.

## When a ball is thrown vertically upward What remains constant?

Solution : When a ball is thrown upward, its acceleration always remains constant which is equal to the acceleration due to gravity.

## What will be the velocity and acceleration of ball upward at maximum height?

Solution : At highest point velocity becomes zero, and acceleration = ncceleration due to gravity `= g = 9.8 ms ^(-2).
