Question

1. which examples best represent newtons first law?

select three correct answers.
a ferris wheel
remains still
until powered
a roller coaster
keeps moving until
stopped
hot air pushes
down, and the
balloon moves up
a ship with more
passengers requires a
greater force to move.
a bumper car stops,
and the rider
moves forward

Explanation:

Newton's first law 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.

• A Ferris wheel (A): Remains still until powered. This shows an object (the Ferris wheel) at rest stays at rest until a force (power) acts on it.
• A roller - coaster (B): Keeps moving until stopped. This shows an object in motion (the roller - coaster) stays in motion until a force (stopping mechanism) acts on it.
• A bumper car (E): When the bumper car stops (due to a force, e.g., collision), the rider moves forward. The rider was in motion (with the car) and when the car stops (acted on by a force), the rider continues in motion (until acted on by another force like the seatbelt).

Answer:

A. A Ferris wheel, B. A roller coaster, E. A bumper car.
