Question

An object always Falls vertically downwards on the earth ?

Answer 1

Answer:

please mark as brainliest

Explanation:

Gravity always acts on the Centre of Mass of an object. The direction of the gravity vector is always directed towards the centre of the Earth. ... Neither the object has any initial Velocity in the horizontal direction, nor does it have a horizontal acceleration.So, the body falls vertically downwards.

Answer 2

Answer:

Acceleration from gravity is always constant and downward, but the direction and magnitude of velocity change. At the highest point in its trajectory, the ball has zero velocity, and the magnitude of velocity increases again as the ball falls back toward the earth

Explanation:

For example, when a ball is thrown up in the air, the ball's velocity is initially upward. Since gravity pulls the object toward the earth with a constant acceleration ggg, the magnitude of velocity decreases as the ball approaches maximum height.



Figure 1. Direction of velocity and acceleration for a ball thrown up in the air. Acceleration from gravity is always constant and downward, but the direction and magnitude of velocity change.

At the highest point in its trajectory, the ball has zero velocity, and the magnitude of velocity increases again as the ball falls back toward the earth (see figure 1).

Common mistakes and misconceptions

People mistakenly think the final velocity for a falling object is zero because objects stop once they hit the ground. In physics problems, the final velocity is the speed just before touching the ground. Once it touches the ground, the object is no longer in free fall.Mark me as branilist
