Answer 1

Newton’s first law of motion states that “An object at rest stays at rest and an object in motion **stays in motion with the same speed and in the same direction** unless acted upon by an unbalanced force.”

Objects tend to “keep on doing what they’re doing.” Because your car is moving at speed, it takes less energy to keep it moving at that speed.
