Gravity | Science for Grade 5 PDF Download

Gravity

• Gravity is the force that pulls objects towards the center of Earth and other planets.
• It is responsible for keeping Earth and other planets in their orbits around the Sun.
• While gravity also exists on the Moon, it is weaker compared to Earth due to the Moon's smaller size.
• For example, when you drop a ball, gravity pulls it towards the ground.

Discovery of Gravity

• Gravity was discovered through observations and experiments over time. 
• One famous example is the story of Isaac Newton observing an apple fall from a tree, which led to his understanding of gravity.

Importance of Gravity

• Gravity is crucial for many aspects of our daily lives. 
• It keeps our feet on the ground and ensures that objects stay in place. 
• Without gravity, everything would float away into space!

Effects of Gravity

• Gravity affects the weight of objects. For instance, an object weighs less on the Moon compared to Earth due to the Moon's weaker gravity.
• It influences the motion of celestial bodies, such as planets, stars, and satellites.
