Rollercoasters are popular attractions at amusement parks. At which position would you experience the most kinetic energy in the diagram below?
Position b would experience the most kinetic energy.
300
What is the Law of Inertia mean?
An object at rest stays at rest until an unbalanced force acts on it.
An object in motion stays in motion until an unbalanced force acts on it.
