Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
If a ball is rolled across the grass on a soccer field, the ball will slow down because of
A
friction
B
inertia
C
the speed of the ball
D
the acceleration of the ball
Explanation: 

Detailed explanation-1: -The frictional force is a contact force that opposes the relative motion of a body. A ball rolling on a grass field slows down due to friction because, the grass field offers frictional force to the ball and makes it to stop.

Detailed explanation-2: -A ball rolling on ground slows down because of frictional force. Frictional force acts opposite to the motion of the ball.

Detailed explanation-3: -A ball rolling on a horizontal surface slows down as it rolls, due to rolling friction.

Detailed explanation-4: -Friction-as the ball rolls, the ball loses its energy to heat and sound. As the energy is lost, the ball slows down and eventually stops.

Detailed explanation-5: -Friction always opposes the motion and reduces the speed at which the object moves on the surface. It will turn some of the kinetic energy of an object into heat energy, thereby reducing the speed.
