• Gravitation: Weightlessness

  This force is also known as weight of the object and is equal to mg where m is the mass of the object and g is the acceleration due to gravity (9.8 m/s^2). An object falls to the ground due to this force only.

• What is the difference between mass and weight? What is frictional force?

  Name at least one method which can be used to simulate weightlessness and describe in detail the forces involved and how they counteract the force of gravity. 1.

• "From the earth to the moon", Jules Verne Physics Problem

  All objects therefore have the same acceleration due to gravity. There is thus NO relative acceleration, once the craft leaves the Earth's atmosphere, and all objects will appear weightless at all times.

• Vestibular Sense

  Therefore, in conditions of weightlessness, the vestibular sense is at least seriously compromised due to the lack of stimulation (e.g., in space travel).

• Weightlessness in airplane

  Answer : (a) Hint : when the centripetal force equals force of gravity then pilot will experience weightlessness.

• Physics: Described frictional force, tension force, centripetal force, weightlessness

  All bodies in the weightless environment experience the same acceleration. The more massive bodies in the surroundings experience a stronger gravitational force, but they also have more inertia , or resistance to acceleration.

• Apparent Weightlessness and artificial gravity: moon's motion around the earth

  10152 Apparent Weightlessness and artificial gravity: moon's motion The moon orbits the earth at a distance of 3.85 x 10^8 m.

• Working with Gravity

  What is the acceleration due to gravity near its surface?

• Planet Tehar, the acceleration of gravity is the same as that on Earth

  Given that Substituting the values in equation Acceleration due to gravity g= -9.8 m/s2( negative sign is because the particle is moving upwards and velocity decreases) Total acceleration = (acceleration due to gravity + acceleration
