1st Law: An object at rest will remain at rest, or an object in motion will remain in motion at constant velocity, unless acted upon by an unbalanced force.
2nd Law: The net force on an object is equal to the mass of the object multiplied by its acceleration. (Force = mass x acceleration or F=ma)
3rd Law: For every action, there is an equal and opposite reaction.

∙ 13y ago- First law: Every body remains in a state of rest or uniform motion (constant velocity) unless it is acted upon by an external unbalanced force. [2][3][4] This means that in the absence of a non-zero net force, the center of mass of a body either remains at rest, or moves at a constant speed in a straight line.
- Second law: A body of mass m subject to a force F undergoes an acceleration a that has the same direction as the force and a magnitude that is directly proportional to the force and inversely proportional to the mass, i.e., F = ma. Alternatively, the total force applied on a body is equal to the time derivative of linear momentum of the body.
- Third law: The mutual forces of action and reaction between two bodies are equal, opposite and collinear. This means that whenever a first body exerts a force F on a second body, the second body exerts a force −F on the first body. F and −F are equal in magnitude and opposite in direction. This law is sometimes referred to as the action-reaction law, with F called the "action" and −F the "reaction". The action and the reaction are simultaneouse

∙ 11y agoBY first law Sir Issac Newton, the father of Scinece has introduced about the importance of force. If no force acts on a body which is at rest, then the body would remain in the same rest state.
Also if suppose a body is already in motion with a uniform velocity then it would continue to do so unless an external force acts on it.
So combinging these two, he states:
"Every body continues in its state of rest or of uniform motion along a straight line unless it is compelled by an external force."

What is common in Sir Isaac Newtons law of motion?
Lift, trust, drag and gravity is the Newtons first law of MotionNewton's laws of motion are:1) Every object in a state of motion will remain in that state unless and external force is applied.2) Acceleration is produced when a force acts on a mass. The greater the mass, of the object being accelerated, the greater the amount of force needed to accelerate the object.3) For every action, there is an equal and opposite reaction.
What were the names of Isaac Newton's three laws of motion?
Newton's First Law of Motion is referred to as the Law of Inertia. It states that an object in motion will stay in motion unless acted upon by an outside force. The Second Law of Motion is the definition of Force : Force=mass x acceleration. The Third Law of Motion is the Law of Reciprocity. It states that forces come in equal and opposite pairs. "Every action has an equal and opposite reaction"
How does newtons 1st law of motion act on the derby car?
An outside force, gravity, pulls the car down the ramp building up speed. At the bottom of the ramp law 1 kicks in. The car continues to move in a straight line.
What is Newtons laws of motion 1?
Newton's first law of motion, also known as the law of inertia, states that an object at rest will stay at rest, and an object in motion will stay in motion with the same speed and in the same direction, unless acted upon by an external force. In simpler terms, an object will remain in its current state of motion (or lack thereof) unless something forces it to change.
What law of of newtons law deal with objects in motion?
The following Newton's law deal with motion. 1. Every body continues in its state of rest or of uniform motion in a straight line path until and unless and external force is applied.It is also called as law of inertia. 2. The rate of change of momentum is directly proportional to the force applied and the change takes place in the direction of applied force. 3. For every action there is an equal and opposite reaction. Forces exist in pairs.

What does newtons 1 law mean in science?
Newton proposed three laws of motion. Newton's 1(first) law of motion-A body continues to be in the state of rest or motion until and unless an external force is applied to change its state.
What sir Isaac newton contribute to science?
Sir Isaac Newton contributed to science by creating the 3 laws of motion, law 1 states "an object in motion stays in motion unless acted upon by a force" Law 2 explains how a force acts on an object. law 3 states "an object that is being pushed or pulled, will be equal on its opposite side.

What were Isaac Newtons 3 laws?
1st Law: Law of InertiaAn object will stay at rest or a constant volocity until acted on by an outside force2nd Law: law of accelerationThe net force on an object is equal to the mass of the object multiplied by its acceleration3rd Law: Law of recipricol actionsEvery action has a equal and opposite reaction1. An object at rest will remain at rest or and object in motion will remain in motion unless acted upon by an unbalanced force. 2. Force=Mass x Acceleration. the bigger the force is the bigger the acceleration will be 3. For every action there is an opposite but equal reaction.

What are three ways that motion can be changed?
According to newtons first law, a body remains in constant motion in the same direction, with the same velocity, unless and until an external force acts on it. So when a body in motion comes under the influence an external force, it either, 1) changes in its speed- accelerate or decelerate. OR 2)changes in direction of motion- like when rolling marbles collide with each other and change direction. OR 3) Both of the above changes takes place. and when a body is in the state of rest, it will remain in rest unless and until acted upon by an external force. (newtons first law)
How does newtons 1st law of motion act on the derby car?
An outside force, gravity, pulls the car down the ramp building up speed. At the bottom of the ramp law 1 kicks in. The car continues to move in a straight line.
What is sir Isaac Newtons 1 law?
Of the Newtons laws of motion the first one states that:(quoting Newton)...every object will remain at rest or in uniform motion in a straight line unless compelled to change its state by the action of an external force. This is normally taken as the definition of inertia. The key point here is that if there is no net force acting on an object (if all the external forces cancel each other out) then the object will maintain a constant velocity. If that velocity is zero, then the object remains at rest. If an external force is applied, the velocity will change because of the force.
What units is measured in force?
forces are measured in newtons
What is newtons 1 st law?
Newton's first law of motion is often stated as: "An object at rest will stay at rest unless acted upon by an outside force. An object in motion will remain in motion at a constant speed and direction unless acted upon by an outside force." Motion, If an object is not ifluenced by any force other then its motion, its velocity will naturally remain constant. i.e, it will continue to move along in a perfectly straight line at a constant speed.
