Newton's 1st law states that an object will remain at rest or in uniform motion unless acted upon by an external force. This law is related to velocity because it explains that an object will only change its velocity if a force is applied to it.
1st law of motion
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 a constant velocity unless acted upon by an unbalanced force.
Newtons first. :^D
Newton has three different laws of motion. The first is the Law of Inertia, the second is the law regarding Mass, Force, and Acceleration, and the third is the law that states "for every action, there is an equal and opposite reaction." Newton's second law is the only one that comes with a formula. The formula is force equals mass times acceleration.
Rest. At rest denotes a constant velocity including velocity of zero. Newton's Law says that a body will change its velocity ,accelerate or decelerate, only when an external force is applied. No force, no acceleration, no change in velocity. At rest itself denotes no force.
mass, acceleration, motion - speed and velocity, newtons 1st law force = mass * acceleration speed requires force to change force acts on velocity to change it newtons 1st law describes force
Newton's 1st law'
The Mathematical equation of Newton's 1st law is : The Conservation of Energy or Equilibrium dE/dr = F= ma = mdv/dt = 0. Thus acceleration is zero when there is no force and no acceleration means no change in velocity or velocity is constant at Equilibrium.
1st law of motion
The Law of Inertia means , No force, No Acceleration (change in velocity) and Vice verso No acceleration (change in velocity), No Force.
Newton's first law of motion states that a body at rest remains at rest and a body in motion remains in motion in a straight line at constant velocity unless acted upon by an unbalanced force.
Velocity.
the body keeps it's state either at rest or moving with uniform velocity , unless affected by external force (newton's 1st law of motion )
No. I assume you mean Newton's Second Law; this law - in the form it is commonly teached in schools - states that F=ma. Assuming mass is constant, that would make force proportional to acceleration - not to velocity. Acceleration is the rate of change of velocity.
Newton's Second law involves acceleration which is changing the velocity. Velocity can be changed in two ways, direction or speed, so Newton's Law applies to both.
When a ball is kicked at an angle, there is no acceleration along the horizontal direction (since there isn't any force along the direction ,ignoring viscous forces), so , its velocity along the horizontal direction remains unchanged.... according to the 1st law , velocity changes only when a net resultant force is applied on the ball , so , Newton's law is valid. only the initial angle of kick and the vertical component of velocity are mainly responsible for the distance travelled by the ball horizontally....
We know that that is the way our Universe works; WHY the Universe was designed that way, or why it happens to be that way, is normally not known.In this case, with a different law for velocity, lots of the physics we know would be drastically different - for example, conservation of energy, conservation of momentum, and conservation of angular momentum could all be violated.
