Motion makes the world go 'round'. When we think of motion we often think of cars, bicycles, kids running, basketballs bouncing and airplanes flying. But motion is so much more. A body is said to be in motion if it changes its position with respect to fixed point or objects around it.
Calculate the speed, velocity and acceleration of an object. Also compare which object is moving faster.
The general study of the relationships between motion, forces, and energy is called mechanics. A force is anything that can change the state of motion of an object, like a push or a pull. You use force when you push a letter on the computer keyboard or when you kick a ball. Forces are everywhere. Forces are measured in Newtons (after Sir Isaac Newton)
Learn about Newtons three laws of motion which relate the forces acting on a body to its motion.
• The first is the law of inertia, it states that every object in motion will stay in motion until acted upon by an outside force.
• The second is commonly stated as force equals mass into acceleration, or F = ma.
• The third and final law is to every action there is an equal and opposite reaction.
