Question

Observations on the movement of the object "marble" when rolled.​

Answer 1

Explanation:

The Concept that can be used to explain the statement is the movement of the object marble when rolled:
Weight applied and Gravity force.

• This can be explained as both objects being lighter considering the weight as a parameter.
• Secondly, it clearly explains the gravity effect that the objects did not fall off.

Answer 2

Answer:

The phenomenon of "force due to gravity" and "rolling friction" can be observed.

Explanation:

Observation from the rolling of a marble:

• Gravitational force is applied to the marble which is of lighter weight and thus it did not fall off due to the gravity.
• Also, the round surface of the marble takes into account the rolling friction.
• Rolling friction: Rolling friction occurs when a wheel, ball, or cylinder rolls freely over a surface. The loss of energy involved in object deformation appears to be the principal cause of friction in rolling.
