Question

Question: Why do objects slow down when there is nothing pushing them?

Observe: Use the Gizmo to explore the question above. Try different objects and surfaces. Each time, turn the fan Off while the cart is moving. (You may find it helpful to pause the Gizmo with the Pause ( ) button, turn the fan off, and then click Play to restart.) 2. Form hypothesis: What causes an object to slow down after no longer being pushed

Answer 1

Answer: Friction

Step-by-step explanation:

For this experiment we will use a concrete surface and a tiled surface.A cart undergoing motion in a concrete surface is brought to rest quicky than a tiled surface.

Hence I can say that the degree of bringing a body in motion is dependent on alot of factors including the nature of the surface.

Recall Newton first law of motion,it points out that for a body to stop there will be a counter balancing force,in this case friction

Answer 2

An object slows down after being pushed due to the energy within the object being used up in doing work against frictional forces between the object and the floor, and work done again viscosity forces between the air molecule and the surface area of the object in contact with the air molecule.

This is in accordance with Newton's first law of motion which states that an object in Motion or rest will continue in that state unless being acted upon by an external force.

Some of the energy is seen to be transformed into heat and sound by these forces forcing the object to slow down and stop if no longer pushed
