The first law of motion is an important part of the physics curriculum. This law applies to all motions that are not subject to unbalanced forces. This concept will be explored later in this chapter. In this quiz, you will need to decide which statement illustrates Newton’s first principle. If you answered ‘c’, then you understand the relationship between mass and weight. For example, a basketball has a mass of about 2.7 kg, while a boulder weighs about 1.6 kg.
Newton’s first law states that an object at rest remains at rest. It also states that an object in motion will stay at a constant velocity until it is stopped. This law is also true for objects at rest, such as a coffee cup. When a car accelerates out from under the coffee, it will stop and spill all over the ground. This law is a fundamental principle of physics, and it explains how our world works.
Newton’s first law also states that an object at rest will remain at rest. In the same way, an object in motion will tend to slow down and stop unless the forces are balanced. Therefore, in order to maintain a uniform speed, an object must have an equal amount of force applied to it. Once a system reaches equilibrium, the forces acting on it will be balanced. If the net force is zero, the object is at rest, or moving at a constant velocity.
Newton’s first law is very simple, but it is not as simple as it seems. For example, a coffee cup will behave the same way as a car does when it is at rest, or vice versa. When the car accelerates, the coffee will spill out of the cup, and the car will continue to move forward. If the engine force is larger than the friction force, then the object will continue to accelerate.
Newton’s first law explains that an object remains at rest and a body in motion stays at a constant velocity. It also explains that when a net force is zero, an object is at rest, or in a constant velocity. In other words, if a net force is zero, then the object is at equilibrium. However, this doesn’t mean that an object is at zero.
A coffee cup behaves the same way as a car. The force on the coffee cup is zero. As a result, the car accelerates and spills the coffee. Similarly, a car’s acceleration will cause a bug to spill a cup of espresso. A person experiencing a collision is a prime example of Newton’s first law. If the driver of a vehicle is not careful, he may end up causing the bug to crash.
