## What is the force of an object thrown upward?

What are the forces acting on a ball thrown upwards? Considering the Air resistance or Drag force negligible, the only force acting on the ball is Gravity i.e. the Gravitational Pull of the earth towards the center of it.

### When we throw a stone up in the air it comes down after reaching a particular height Why is it so?

When the stone travelling vertically upwards, it is experiencing the retardation due to gravity. After reaching maximum height, the stone descends with zero initial velocity, accelerated downwards due to gravity and reaches the ground after time t’.

**What kind of force is applied when throwing a ball?**

Contact forces involve push, pull and friction. A contact pull and friction. A contact force is when two interacting objects are physically touching, for example: when you are throwing a ba throwing a ball you are using a contact force.

**How do you find the force of a thrown object?**

Multiply mass times acceleration. The force (F) required to move an object of mass (m) with an acceleration (a) is given by the formula F = m x a. So, force = mass multiplied by acceleration.

## What happens when a stone is thrown upwards in terms of its velocity and acceleration?

Projectile motion is the motion of an object where the size or magnitude of the vertical acceleration is g and the horizontal acceleration is zero. A stone thrown in the air follows a projectile motion. It goes upwards against a deceleration of size g which slows it down until it comes to a stop at the maximum height.

### When a ball is rising upward after you toss it vertically the net force on the ball is equal to the force of gravity on the ball?

When a ball is rising upward after you toss it vertically, the net force on the ball is equal to the force of gravity on the ball. You pull horizontally on a rope, attached firmly to a hook on the wall, with a force of magnitude 16 N….Figure 2.

**What is the maximum height of the stone thrown straight up?**

The maximum height in meters reached by the stone thrown straight up with a speed of 35 m/s is 62.5 m as solved by my computer program. The answer is inside the box labelled as dymax. Vo = 35 m/s; the angle theta is 90 degrees and the value of the acceleration due to gravity g is 9.8m/s^2.

**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 is the velocity at which the first stone meets the second?

Two stones are thrown vertically upward from the same point with same velocity of 20m/s, at an interval of 2sec after one another.The first stone meet second stone moving upward at 20m/s.What time will the second stone take to meet the first stone? Let t be the time taken by the second stone.

### What is the initial velocity when a rock is thrown upward?

Since up is positive, and the rock is thrown upward, the initial velocity must be positive too. The acceleration due to gravity is downward, so is negative. It is crucial that the initial velocity and the acceleration due to gravity have opposite signs.
