Friction is the force that opposes motion.

<h3>What is friction?</h3>

The term friction refers to the force that hinders the movement of a surface over another. The frictional force depends on the nature of the surfaces in contact.

1) The two forces acting on the ball during the frictional force are the forward force and the frictional force.

2) The ball takes more time to roll down the incline in the presence of the cloth because of the increase in friction of the surface.

3) The students repeated the investigation there times in order to ensure accuracy of the results.

4) The energy of the ball changes from potential energy at the top of the ramp to kinetic energy as it rolls down the ramp.

Answer:

same as

Explanation:

According to Newton's 3rd law, the force that the Earth exert on the Sun would be equal (and in opposite direction) with the force that the Sun exerts on the Earth.

Also Newton's gravitational law states the formula for the attraction between objects with mass, is the same for both objects

Andrew [12]

Answer: Speeding Up

Explanation:

Force is proportional to the acceleration of an object. The greater the force, the more acceleration will be produced.

When the force on the tire is equal to the weight of the car, the car is reaching a stability as a result of increase in motion.

But when the force of the load on the tire is quite large(most likely several times the weight of the car) and is directed forward, then, the car is at high speed.
