Difference between work done against gravity and friction

mario62 [17]

Mark Brainliest please

Friction is a nonconservative force. Therefore work done against friction cannot be stored as potential energy and later converted back to kinetic the way work against gravity can.

Gravity always pulls objects such as a desk, book or person down. Thus, when you jump, gravity causes you to land on the ground. Friction, however, doesn't pull objects down. ... Instead friction occurs when something like a machine or individual pulls a sliding object in the opposite direction of another object.

Friction and gravity exist in every aspect of a person’s life. For example, almost every movement you make, such as walking and running, involves friction. When you throw a ball up, gravity causes the ball to fall down. A person sliding a book across a table creates friction. Nevertheless, differences between gravity and friction also exist. Force affects gravity and friction in different ways.

A 2400-kg satellite is in a circular orbitaround a planet. The

Fofino [41]

Answer

given,

mass of satellite = 2400 Kg

speed of the satellite = 6.67 x 10³ m/s

acceleration of satellite = ?

gravitational force of the satellite will be equal to the centripetal force

$F = \dfrac{mv^2}{r}$

$F = \dfrac{2400\times (6.67\times 10^3)^2}{r}$

Assuming the radius of circular orbit = 8.92 x 10⁶ m

now,

$F = \dfrac{2400\times (6.67\times 10^3)^2}{8.92\times 10^6}$

F = 11970.11 N

acceleration,

$a = \dfrac{F}{m}$

$a = \dfrac{11970.11}{2400}$

a = 4.98 m/s²

An object that is moving in a linear path with an acceleration in the direction of motion has a(n) ______________ velocity. cons

Kamila [148]

The correct answer is increasing velocity.

In fact, the fact that the object has an acceleration different from zero means that the velocity of the object is changing. If the acceleration is in the direction of the motion, then it is a positive acceleration, therefore the velocity is increasing. The law of velocity for an object in accelerated motion is in fact
$v(t)=v_0 + at$
where $v_0$ is the initial velocity, a the acceleration and t the time. When a is positive (same direction of the motion), then the term (at) is increasing as t becomes larger, therefore the velocity v(t) is increasing as well.
