A careful observation of the question given above,
Then context of the question suggests that Newton only observed the action of a prism on white light and on red light meaning he did not influence or control the event. Now, because he did not control the event, his investigation is only term observational study of the action of a prism on white light and on red light.
Newton observed the action of a prism on the white light and on red light. Because he did not control the event, this investigation of light was an observational study.
The ball because the Kinetic Energy transfers from the bat to the ball, increasing the movement and acceleration of the ball because of the Kinetic Energy transferred from the origin force (The bat)
the heat always transfers from high temperature to low temperature body without aid of any external energy to this law the heat transfers from cup of coffee to the person body until both bodies reaches to the equilibrium state
