That depends on the reference we take.....If we take the velocity upwards to be +ve than the velocity downwards will be negative and vice versa....

Why does an object accelerate when it falls toward as the earth's surface?

An object accelerates when it falls towards the Earth's surface due to the force of gravity acting on it. Gravity pulls the object towards the center of the Earth, causing it to increase in speed as it falls.


Why does and object accelerate when it falls toward Earth's surface?

An object accelerates when it falls towards Earth's surface due to the force of gravity acting on it. Gravity causes a constant acceleration of 9.8 m/s^2, pulling the object towards the center of the Earth. As the object falls, the force of gravity remains constant, leading to a continuous increase in the object's speed and acceleration.


As a ball falls toward earth the momentum of the ball increases How would you reconcile this observation with the law of conservation of momentum?

The principle of conservation of momentum is not satisfied, since the sum of external forces is not equal to zero, if the ball falls the net force is equal to the weight, makes the ball Vary your speed and therefore their momentum.


The speed at which an object falls and the acceleration at which it falls are always the same value?

The speed at which an object falls and the acceleration at which it falls are not the same value. The acceleration due to gravity is constant at about 9.8 m/s^2 near the surface of the Earth, but the speed of an object can change as it falls depending on factors such as air resistance.


Does the mass make a difference to the speed at which something falls to Earth?

No, the mass of an object does not affect the speed at which it falls to Earth. All objects fall at the same rate of acceleration due to gravity, regardless of their mass. This principle is known as the equivalence principle.

What forces act upon a meteor as it falls toward Earth?

As a meteor falls toward Earth, the main forces acting on it are gravity and air resistance. Gravity pulls the meteor downward, accelerating its descent. Air resistance, or drag, counteracts this motion by pushing against the meteor as it moves through the atmosphere, slowing it down. These forces together determine the meteor's speed and trajectory as it nears the Earth's surface.

What does gravity do to objects that fall toward earth?

Gravity pulls objects toward the center of the Earth, causing them to accelerate as they fall. This acceleration increases their speed until they reach the ground or another surface.


Why do the satellites not fall while revolving around the earth?

. The speed of the satellite is adjusted so that it falls to earth at the same rate that the curve of the earth falls away from the satellite. The satellite is perpetually falling, but it never hits the ground!


Why do skydivers reach a top speed?

as a skydiver falls to the earth,there is air friction in the opposite direction to the force of gravity pulling him towards the earth. As he falls to earth he reaches a higher & higher speed up until the point at which the force of friction caused by air (upwards) is the same as or equals the force of gravity (downwards) and he cannot accelerate any further..ie he reaches a top speed


What is the speed of Niagara Falls?

What is stopping the sun from dragging the earth into the sun?

the earths shape, the earths size, the earths position, and a few other things. Short answer: the Sun is dragging the Earth toward itself, but the Earth's speed causes it to fall around the Sun in an orbit instead. The Sun's gravitational pull is dragging the Earth (and all the other planets) toward itself. The Earth is moving, and it's speed and direction prevent it from falling closer toward the Sun; instead, it falls around the Sun in an orbit, much like a basketball rolling around the rim of a basket. It works something like this: If the Sun's gravity were suddenly gone, the Earth would move in a (more or less) straight line at a right angle to the direction of the Sun. Because the Sun's gravity is pulling on the Earth, it bends the Earth's velocity vector (direction of movement) in toward the Sun, in the same way a ball thrown straight and level will start to curve toward the ground. As the Earth keeps moving at right angles to the Sun, the Sun's gravity continues to bend the direction of the Earth's movement around itself. The The Earth's speed is such that it continues to fall around the Sun in a (more or less) stable, continuing orbit, like a ball being spun at the end of a string.


How are gravity and speed related?

Gravity and speed are related in the context of how gravity affects the speed of an object. As an object falls towards the Earth, it accelerates due to gravity, increasing in speed as it falls. The speed of an object falling due to gravity depends on factors such as the object's mass and the strength of the gravitational force acting on it.
