Answer:
Gravity: The force of gravity is what keeps us on the ground and causes objects to fall to the ground when dropped.
Friction: Friction is the force that resists motion when two objects are in contact with each other. For example, the friction between your shoes and the ground allows you to walk.
Tension: Tension is the force that is transmitted through a rope or cable when it is pulled tight. For example, the tension in a rope is what allows a flag to be raised on a flagpole.
Normal force: The normal force is the force that a surface exerts on an object in contact with it. For example, the normal force of a book on a table is what keeps the book from falling through the table.
Electric force: The electric force is the force that exists between two charged objects. For example, the electric force between a positively charged balloon and a negatively charged wall is what causes the balloon to stick to the wall.
Magnetic force: The magnetic force is the force that exists between two magnets or between a magnet and a magnetic material. For example, the magnetic force between a refrigerator magnet and a refrigerator door is what allows the magnet to stick to the door.
Step-by-step explanation:
In physics, a force is any influence that can cause an object to undergo a change in motion or deformation. Here are some practical examples of forces:
