Force is a push or pull that can change the motion of an object. It is measured in Newtons (N).
Imagine you're pushing a shopping cart. The harder you push, the faster the cart moves. The force you apply determines how much the cart accelerates.
Mass: Mass is the amount of matter in an object. It determines how much force is needed to accelerate an object.
Friction: Friction is a force that opposes motion between two surfaces in contact. It can slow down or stop objects from moving.
Gravity: Gravity is a force that attracts objects towards each other. It keeps us grounded on Earth and affects the motion of objects in space.
