Embrace the Force of Gravity: Understanding the Power Behind Movement

What force causes a wagon to speed up as it rolls down a hill?

A) friction

B) gravity

C) mass

D) normal

The force that causes a wagon to speed up as it rolls down the hill is:

The correct answer is B) gravity.

Gravity is a powerful force that affects everything with mass. It is the force that pulls objects towards the center of a planet, like the Earth. Without gravity, objects would float away or not move at all.

Scientists define gravity as the force that keeps planets in their orbits around the Sun. Everything that has mass has gravity, including humans. This is why we stay grounded on the Earth's surface and why objects always fall downwards.

When a wagon rolls down a hill, gravity is the force behind its acceleration. Gravity pulls the wagon downwards, causing it to speed up as it moves along the slope. This natural force is responsible for the motion and speed we observe in everyday phenomena like this.

So next time you see a wagon rolling down a hill, remember the invisible force of gravity that is at work, making it move faster and faster with every passing moment.
