A SCIENCE NOTE
The acceleration of climate change is similar to a snowball. When a snowball rolls down a hill, its momentum is governed by several principles of physics, including conservation of momentum, friction, and the laws of motion. The laws of motion were formulated by Sir Isaac Newton in the 17th century and form the foundation of classical mechanics. They describe the relationship between the motion of an object and the forces acting upon it. There are three laws:
Newton’s First Law (Law of Inertia):
A body at rest stays at rest, and a body in motion stays in motion with a constant velocity, unless acted upon by an external force.
- This means that objects will not change their state of motion unless a force acts on them.
- For example, a ball rolling on a flat surface will eventually stop due to friction (an external force).
Newton’s Second Law (Law of Force and Acceleration):
The acceleration of an object is directly proportional to the net force acting on it and inversely proportional to its mass.
- Mathematically: F = ma, where:
- F is the net force (in newtons),
- m is the mass of the object (in kilograms),
- a is the acceleration (in meters per second squared).
- This explains why heavier objects require more force to accelerate than lighter ones.
Newton’s Third Law (Action and Reaction):
For every action, there is an equal and opposite reaction.
- This means that forces always occur in pairs. If object A exerts a force on object B, object B exerts an equal and opposite force on object A.
- For example, when you push against a wall, the wall pushes back with an equal force.
Together, these laws form the basis for understanding motion and the effects of forces in our physical world. They apply to a wide range of phenomena, from everyday movements to planetary orbits, as long as the speeds involved are much slower than the speed of light and the scales are larger than atomic.
