Question

Explain the term force with example.

Answer 1

Force

1. A force is a push or pulls on an object that causes it to move faster or slower, halt, change direction, or change size or shape.
2. Nothing would ever move without force.
3. Force is a vector quantity as it has both magnitude and direction.
4. The basic equation of motion in classical mechanics is Newton's second law, which states that the force F acting on a body is equal to the mass m of the body multiplied by the acceleration and its center of mass, $F=m\times a$.
5. SI unit of force is 1 Newton.
6. Consider an example from our daily lives while riding our bicycles. When we press the pedal, there is a force.
7. Brushing our hair is another example. When brushing hair, the hairbrush exerts a force on the hair.
