Zoomling — Gravity & Noncontact Forces Gravity Drop Gorge

Hi!

I'm Zoomling.

Welcome to Gravity Drop Gorge!

Will you help me investigate gravity & noncontact forces?

The Grumblies have mixed up our clues.

Let's check the evidence!

Gravity is an attractive force.

Near Earth's surface, unsupported objects are pulled toward Earth.

Which force explains the falling ball?

  • A. Only friction with a table
  • B. A change in the ball's name
  • C. Gravity

The answer is C: Gravity

Some forces act without direct contact.

Gravity and magnetic attraction are examples;

a hand pushing a cart is a contact force.

That clue helps us make sense of this place.

Some forces act without direct contact.

Gravity and magnetic attraction are examples;

a hand pushing a cart is a contact force.

Which is a contact force?

  • C. Gravity pulling a falling ball

The answer is B: A hand pushing a cart

Hmm...

how does that connect to our first clue?

Our digital model releases a ball

and shows it falling toward the ground.

The player does not need to drop real objects or

approach a dangerous height.

Can a magnetic force act without touching?

  • A. Yes
  • B. No
  • C. Only if tied by a rope

The answer is A: Yes

Some forces act without direct contact.
