Air resistance of an object can slow its fall. If every object had the same resistance, everything would fall at the same speed.
What else can I help you with?
What is true about an objects fall velocity as it approaches the earth's surface?
As an object falls towards the Earth's surface, its velocity increases due to the acceleration caused by gravity. Near the surface, the object will reach a terminal velocity where the force of air resistance equals the force of gravity, causing the object to fall at a constant speed.
Why do all objects fall to earth at the same time velocity even though the acceleration due to gravity always stays the same?
All objects fall to Earth at the same velocity under gravity because they experience the same acceleration due to gravity, which is 9.8 m/s^2 near the Earth's surface. This means that regardless of their mass, they will accelerate towards the Earth at the same rate, resulting in the same final velocity when they hit the ground.
What occurs when objects free fall near the Earth and surface?
Objects in free fall near the Earth experience gravitational acceleration that causes them to accelerate toward the Earth's surface at a rate of 9.8 m/s^2. As they fall, they gain kinetic energy and their speed increases until they reach terminal velocity or hit the ground.
Why don't all objects fall to the earth at the same velocity though the acceleration due to gravity always stays the same?
because of the differences in air resistance.
Who discovered that all objectsheavy or lightfall the same velocity?
Galileo Galilei was the first to explain that heavy and light objects would fall the same way in a vacuum. Keep in mind, objects do not fall with 'velocity,' but with 'acceleration.'
Is terminal velocity the same speed for any weight?
Terminal velocity for a feather will be considerably lower than the terminal velocity of a bullet. The size and shape of the object will play an important role. While objects dropped from a given height in a vacuum will fall to earth at the same velocity, the resistance caused by atmosphere will be different for different objects.
Why does gravity change velocity?
Gravity changes velocity because it accelerates objects towards the Earth at a rate of 9.81 m/s^2. As objects fall, their velocity increases due to this gravitational acceleration. Conversely, when objects move against gravity, such as when thrown upwards, gravity decreases their velocity until they eventually stop and fall back down.
Why don't all objects fall to earth to the same velocity even though the acceleration due to gravity always stays the same?
because of the differences in air resistance.
How objects fall on Earth and on the moon?
Objects fall towards the ground due to gravity on both Earth and the moon. However, the acceleration due to gravity is higher on Earth than on the moon, so objects fall faster on Earth compared to the moon. Additionally, the lack of atmosphere on the moon affects the way objects fall by reducing air resistance.
Why don't all objects fall to the earth at the same velocity even though the acceleration due to gravity always the same?
because of the differences in air resistance.
Why don't all objects fall to the earth at the velocity even though the acceleration due to gravity always stays the same?
The air resistance for objects of different shapes causes a force which accounts for this. A leaf is a good example of an object with large surface area. A parachute - before and then after it is opened it another example. In a vacuum, such as on the Moon, all objects do fall at the same speed. One of the Apollo astronauts dropped a hammer and a feather at the same time; both reached surface together. Maybe you can find a YouTube showing this.
Why don't all objects fall to earth at the same velocity even though the acceleration due to the gravity always stay the same?
because of the differences in air resistance.
