Is gravitational force acting on a person who falls off a cliff or on an astronaut inside an orbiting space shuttle?
Yes, gravitational force is acting on both the person falling off a cliff and the astronaut inside an orbiting space shuttle. The person falling off a cliff experiences a gravitational pull towards the center of the Earth, causing them to accelerate downwards. The astronaut inside an orbiting space shuttle experiences a gravitational pull towards the Earth as well, but their motion is primarily governed by their speed and centripetal force that keeps them in orbit.
How do you describe forces acting on an apple?
its called gravity person
What two forces compress a spring inside a weighing scale when you weigh yourself?
The two forces that compress a spring inside a weighing scale are the force of gravity acting on the person standing on the scale and the reaction force exerted by the spring in the scale to counteract the force of gravity. This compression of the spring is used to measure the weight of the person.
Is there gravity where space shuttles orbit?
A very low level, called microgravity, that's a small fraction of normal gravity. Astronauts feel weightless, by comparison. Space shuttles orbit at a distance of 100-200 miles above the Earth. The shuttle is actually falling toward the Earth all the time, but the speed of its orbit keeps it from falling any closer. Don't confuse gravity with weight. The Earth's gravity extends to the outer reaches of the Solar System. Earth's gravity is what keeps the satellites which are orbiting the Earth from flying away into space. "Weight" is measure of the local acceleration due to gravity. When a person is in orbit, inside a shuttle, he is falling along with the shuttle at about 17,000 miles per hour. The mass of the shuttle and the mass of the person are attracting each other with 'micro-gravity' which is a million times less than the gravity of the Earth.
What is the effect of gravity on the weight of an object when a person is standing upright?
When a person is standing upright, gravity pulls the person and the object they are holding towards the Earth. This causes the weight of the object to increase due to the force of gravity acting on it.
Do people weigh less on the moon than on earth?
Yes, there is much less gravity on the moon.Yes. A person's mass does not change but, because weight factors in the force of gravity acting on the person's mass, their weight is different on the moon. The moon creates a smaller force of gravity, therefore, a person's weight is lower on the moon.
How is acceleration due to gravity be zero in a parachute?
In the case of a parachute, the person and parachute fall at a constant speed once the forces acting on them are balanced. This means that the net acceleration, including gravity, is zero. Gravity is still acting on the person and parachute, but it is balanced by the drag force exerted by the parachute, resulting in a constant speed descent.
Is gravitational force acting on a person who falls off a cliff?
Yes, gravitational force is acting on a person who falls off a cliff. The force of gravity accelerates the person downwards towards the Earth until another force, like air resistance or the ground, counteracts it.
What is the transformation energy of a person lifting a chair?
The transformation energy of a person lifting a chair comes from the metabolic energy produced within the person's body, which is converted into mechanical energy to raise the chair against gravity. This energy is used to do work and overcome the force of gravity acting on the chair.
Why the weight of a person is less in mines?
the weight of a body depends upon the value of g at a place.the value of g(gravity) decrease when we go inside the earth.therefore the weight of a person is less in mines.
A person is standing still away from a shuttle launch site. As the shuttle heads towards space the shuttle is getting smaller. What happens to the shadow of the shuttle?
Disappears.
If a cable snaps in an elevator and starts falling will the person inside float?
No, the person inside the elevator will not float. Objects in freefall experience weightlessness, but the person will still accelerate downward due to gravity. The experience will feel like weightlessness, but they are still subject to gravity's pull.
