# Newton’s First Law – Examples, PDF

Professor Newton posited three laws of motion that have reshaped various facets of our life, which allowed us to have various machines and gadgets that utilize these laws. Newton’s first law deals with inertia, while Newton’s second law deals with force and acceleration. Newton’s third law deals with the action and reaction of force.

## What Is Newton’s First Law?

Newton’s first law of motion states that an object at rest will stay at rest unless acted upon by an imbalanced external force. The same is true for objects in motion as they will stay in motion on a straight line until acted upon by an imbalanced external force. This law of motion has many applications in various contexts, themes, and tones that have many implications for the action. A lot of previous researchers have applied the scientific method to prove this law of motion.

## How to Solve the Equation for Newton’s First Law

Force is the amount of strength and kinetic energy an object, entity, or phenomenon uses to impact and move a specific object or entity. The of the person will dictate the amount of force the said person can exert. Inertia has an equation of F = dp/dt where F is force, p is pressure, and t is time. Momentum also has an equation of P = mv where m is the mass and v is the velocity.

### Step 1: Familiarize Yourself with the Formula

Newton’s first law of motion utilizes the formula of F = dp/dt, which will act as the outline or outline format for the whole formula. You will also need to know that p = mv, which means you can substitute these values to create a new equation of F = d(mv)/dt.

### Step 2: Identify the Variables of the Question

You must identify the variables in the question, which you will isolate to ensure that you won’t make any mistakes in the substituting part of the equation. You must also ensure each variable has the correct mode of measurement, if it isn’t then you must convert them accordingly.

### Step 3: Substitute the Variables into the Formula

After you have identified the variables in the question, you must substitute these said variables into the formula. If you are missing the variable for pressure, you can use the modified version of the formula without the variable for pressure.

### Step 4: Answer the Equation

After you have finished substituting the variable for the formula, you must answer the equation by using the correct operations. The answer should also have the correct mode of measurement, if it doesn’t then you must convert it accordingly.

## What are real-life examples of Newton’s first law in action?

There are many innovations and modern-day gadgets that utilize Newton’s law of inertia to either help or benefit the people using them. Cars have seat belts, which will apply a specific amount of force. This will stop the person from moving forward and injuring themselves whenever an accident occurs.

## What happens to inertia when there is no gravity?

Gravity has a constant force that will push objects and entities toward a specific planet. Objects or entities that have no acting gravity will not be pushed down or grounded to a surface directly below them. Objects that are in motion will infinitely move in a specific direction at a constant rate or pace.

## What phenomenon a person can observe, which will explain Newton’s first law of motion?

When a person throws an object in a specific direction, the said object will slowly decelerate as acceleration and gravity will slowly ground the object to rest. A lot of animals use this method to defend themselves from other predators or threats.

Newton’s first law of motion is the law of inertia where an object at rest will remain at rest unless an object or an entity with an imbalanced force will act on it. The same is true for objects in motion. It is important to know and understand Newton’s first law of motion as these things have many applications.
