Final answer:
A force is a push or a pull on an object that causes it to accelerate, decelerate, or change its shape.
Step-by-step explanation:
A force is a push or a pull on an object that can cause it to accelerate, decelerate, or change its shape.
For example, when you kick a soccer ball, you apply a force that causes the ball to move. Similarly, when you pull a door open, you exert a force to move the door.
Forces can be contact forces, such as when you physically touch an object, or non-contact forces, such as magnetism or gravity. In physics, forces can be described and measured using Newton's laws of motion.
