What are 3 factors that affect the gravity at a specific location?
Gravitational Factors of Our Eight Planets Two major factors, mass and distance, affect the strength of gravitational force on an object.
What factors affect Centre of gravity?
Factors affecting Stability: Relationship of line of gravity to base of support. The height of then Center of Gravity. The size and shape of base of support. The mass of the body.
Does Centre of gravity depend on shape?
Center of gravity is a point on which behaves as if the whole weight of the body appears to be concentrated. So, it depends upon its mass, weight and geometry (i.e. shape)
Why does Centre of gravity change?
Centre of Gravity The Center of Gravity (COG) is an imaginary point around which body weight is evenly distributed. The center of gravity of the human body can change considerably because the segments of the body can move their masses with joint rotations.
What are the principles of gravity?
Newton’s law of universal gravitation is usually stated as that every particle attracts every other particle in the universe with a force that is directly proportional to the product of their masses and inversely proportional to the square of the distance between their centers.
How does gravity affect my body?
Gravity and the Body Gravity affects many parts of your body as you age. It compresses the spine, contributes to poor blood circulation and can decrease your flexibility. The gravitational pull also affects your organs, causing them to shift downward, away from their proper position.
How do humans respond to gravity?
Human muscles adapt to new situations. Thus, in microgravity, tension is reduced on muscles that support the body against gravity, resulting in a loss of muscle mass and an accompanying loss of muscle strength.
What are 4 actions that are affected by gravity?
Some examples of the force of gravity include:
- The force that holds the gases in the sun.
- The force that causes a ball you throw in the air to come down again.
- The force that causes a car to coast downhill even when you aren’t stepping on the gas.
- The force that causes a glass you drop to fall to the floor.
What happens when gravity is zero?
A lack of gravity would eventually take its toll on our very planet, writes Masters. “Earth itself would most likely break apart into chunks and float off into space.” Without the force of gravity to hold it together, the intense pressures at its core would cause it to burst open in a titanic explosion.
Can you move in zero gravity?
If you are stationary in space with nothing around you to push off on, you cannot move yourself by pushing on yourself. But you can twist your body around its center of gravity – you just can’t move your center of gravity. On Earth, we can walk forward because we push on the Earth and it pushes back on us.
Can things move in a vacuum?
it is ideally not possible moving in a vacuum or inside a space made of vacuum, for vacuum is an enclosed space where there is no object and pressure is zero; presence your body except your mind inside it will clash with the basic requirements of vacuum. in general vacuum is absence of air.
Can you swim in 0 gravity?
There is no “up” or “down” in zero gravity. In fact, if you’re swimming (literally) while in space, there’s not even a “sideways” or “crooked.” There’s no gravity for the fish to orient itself. So NASA took live fish up to space and let them swim around in zero gravity.
