Gravity Uncovered: Why Things Fall
What do you already know about gravity?
Learning Objectives
At the end of the lesson you will be able to explain what gravity is, describe how it affects objects on Earth, and provide real-life examples of gravity in action.
What is Gravity?
Gravity is an invisible force that pulls objects towards one another. On Earth, gravity makes things fall to the ground.
Newton and the Apple
Sir Isaac Newton famously wondered why apples fall down instead of up. He realised it was due to gravity.
Where Do We See Gravity?
Gravity holds the Moon in orbit and causes planets to move around the Sun.
Everyday Examples
Space Examples
Jumping, dropping a ball, or pouring water all involve gravity. It keeps us on the ground.
Gravity Everywhere
Gravity affects everything with mass, not just on Earth. That’s why things fall on other planets too.
Gravity is Different Elsewhere
Gravity can be stronger or weaker depending on the planet. The Moon’s gravity is weaker than Earth’s, so astronauts bounce!
Let’s Investigate: Gravity in Action
With a partner, drop two different objects (like a pencil and an eraser). What do you notice about how they fall?
Key Points to Remember
Gravity is a force that pulls things together. It is why we stay on the ground and why objects fall when dropped.
