Force is a push or pull that can cause an object to accelerate, change direction, or deform. It is a vector quantity, meaning it has both magnitude and direction. Force is measured in units of newtons (N) and is described by Newton's laws of motion.

Force is an influence that can change the motion of an object. A force can be a push or a pull, and it can be applied to an object in any direction. Forces are measured in units called newtons (N).
There are four fundamental forces in nature:
- Gravitational force: The force that attracts objects with mass towards each other.
- Electromagnetic force: The force that attracts or repels objects with electric charge.
- Strong nuclear force: The force that holds the particles in an atomic nucleus together.
- Weak nuclear force: The force that is responsible for certain types of radioactive decay.
Forces can be applied to objects in a variety of ways. For example, a force can be applied to an object by:
- Contact: When two objects touch each other, they can exert force on each other. For example, when you push on a wall, you are applying force to the wall.
- Gravity: Gravity is a force that attracts objects with mass towards each other. For example, the Earth's gravity pulls us down towards the ground.
- Electromagnetism: Electromagnetism is a force that attracts or repels objects with electric charge. For example, magnets can attract or repel each other because they have electric charges.
Forces can have a variety of effects on objects. For example, forces can:
- Change the speed of an object. For example, when you push on a ball, you can increase its speed.
- Change the direction of an object. For example, when you throw a ball, you can change its direction.
- Change the shape of an object. For example, when you squeeze a ball, you can change its shape.
Forces are essential for everyday life. Without forces, we would not be able to move, eat, or breathe.
