Example: When you push a toy car, you apply force to make it roll forward. If
you pull a wagon, you use force to move it toward you.
The Role of Gravity
Gravity: Gravity is a force that pulls everything toward the Earth. It is what
keeps us grounded and stops us from floating away!
Example: When you jump, you go up for a moment, but gravity pulls you back
down to the ground. That’s why you land back on your feet after jumping.
Understanding Friction
Friction: Friction is a force that
occurs when two surfaces rub
against each other. It can slow
down or stop moving objects.
Smooth Surfaces: When you slide
on ice, there’s less friction, so you
can glide easily.
Rough Surfaces: On a grassy field,
there’s more friction, making it harder to slide or roll things, like a ball.
Types of Movement
1. Straight Line: Movement in one direction, like a bicycle going straight down
the street.
2. Curved Path: Movement in a curve, such as a roller coaster going around a
bend.
