What word means attractive?
beautiful, alluring, glamorous, lovely, inviting, fair, enticing, interesting, charming, pleasant, good-looking, tempting, gorgeous, engaging, pleasing, handsome, adorable, agreeable, comely, enchanting.
Is negative force attractive?
Of course, the gravitational force is always attractive, so this minus sign is always present, but in different kind of forces such as Coulomb force, a negative module means an attractive force while a positive module means a repulsive one, and the sign of the module comes from the sign of the charges.
What is force of attraction?
Force of attraction is a force that pulls the body near due to its attraction. Some of them are magnetic force, electric force, electrostatic force and gravitational force. Gravitational force is very well-identified instance force of attraction as it draws objects towards itself regardless of its distance.
Why is gravitational potential energy always negative Class 11?
Gravitational potential energy is negative at the surface of Earth, because work is done by the gravitational field in bringing a mass from infinity i.e work has to be done on a body, if it is taken away from the gravitational field of the earth. Thus, potential energy is negative.
What is negative potential energy?
Now, we can define the electric potential energy of a system of charges or charge distributions. Therefore, a system consisting of a negative and a positive point-like charge has a negative potential energy. A negative potential energy means that work must be done against the electric field in moving the charges apart!
Can you have negative gravitational potential energy?
The gravitational potential energy could even be negative if the object were to pass below the zero point.
What is gravitational potential energy derive an expression for it?
Since the force required to lift it is equal to its weight, it follows that the gravitational potential energy is equal to its weight times the height to which it is lifted. PE = kg x 9.8 m/s2 x m = joules.
What are the units of gravitational potential?
Gravitational potential energy
- gravitational potential energy is measured in joules (J)
- mass is measured in kilograms (kg)
- height is measured in metres (m)
- gravitational field strength (g) is measured in newtons per kilogram (N/kg)
What is the traditional definition of gravity?
Gravity has traditionally been defined as a force of attraction between things that have mass. The strength of gravity between two objects depends on their mass and their distance apart. Earth’s gravity constantly pulls matter toward the center of the planet.
What is the adjective of gravity?
adjective. /ˌɡrævɪˈteɪʃənl/ /ˌɡrævɪˈteɪʃənl/ connected with or caused by the force of gravity.
