A student leaves a pencil on a desk and the pencil stays in the same spot until another student picks it up.
Law of Inertia
Law of Acceleration
Law of Interaction
Pushing a child on a swing is easier than pushing an adult on the same swing, because the adult has more mass and requires more force to accelerate.
Law of Inertia
Law of Acceleration
Law of Interaction
A book rests on a table. The force of gravity pulls down on the book with a force of 20 newtons. What prevents the book from accelerating downward at 9.8 m/sec2?
The table presses back up on the book with an equal and opposite force of 20 newtons.
The table presses back up on the book with a force greater than 20 newtons.
The table and the book together are accelerating downwards at 9.8 m/sec2.
The inertia of the book holds it up.
