Newton's first law of motion is that an object moving at a constant velocity keeps moving at that velocity unless an unblanced force acts on it. Newton's second law of motion is that the acceleration of an object is in the same direction as the net force on the object. Newton's third law of motion is when one object exerts a force on a second object, the second one exerts a force on the first that is equal in strength to the opposite in direction.

1. An object at rest remains at rest and an object in motion continues in motion with constant velocity unless experiences a net external force.

2. The acceleration of an object is directly proportional to the net force and inversely proportional to objects mass.

3. For every action, there is an equal and opposite reaction.

Every object in a state of uniform motion tends to remain in that state of motion unless an external force is applied to it.

The relationship between an object's mass m, its acceleration a, and the applied force F is F = ma. Acceleration and force are vectors (as indicated by their symbols being displayed in slant bold font); in this law the direction of the force vector is the same as the direction of the acceleration vector.

for every action there is an equal/opposite reaction

Newton's three laws of motion are:
The first one is: THe motion of an object does not change unless an unbalanced net force acts upon it. The second one is: the acceleration of an object is in the same direction as the net force on the object. The third one is: when an object exerts a force on a second object, the second one exerts a force on the first that is equal in strength and opposite direction.

1. An object at rest, stays at rest until acted upon by a force.

2.The acceleration of an object is directly proportional to the net force and inversely proportional to an object's mass.

3. For every action, there is an equal and opposite reaction

Newton's first law of motion states that an object moving at a constant velocity keeps moving at that velocity unless an unbalanced net force acts on it. THe second one is that the acceleration of an object is in the same direction as the net force on the object. The third one states that when one object exerts a force on a second object, the second one exerts a force on the first that is equal in strength and opposite in direction. THose are the 3 laws.

An object at rest remains in rest and an object in motion remains in motion unless acted upon an external force

the acceleration of an object is dirreclty effect by the amount of net force it recieves

for every action there is an equal and opposite reaction.

Newton's three laws of motion are 1) An object at rest remains at rest, and an object in motion continues in motion with constant velocity unless it experiences a net external force. 2) The acceleration of an ovject is dirctly proportioned to the net force and inversely proportional to an object's mass.
3) For every action, there is an equal and opposite reaction.

Newtons first law is the law of inertia or that a object in motion will stay in motion unless acted on by a force. His second law is that the accelaration of an object is in the same direction as the net force on the object. Newtons third law is when one object exerts a force on a second object, the second one exerts a force in the opposite direction.

~Newton's Three Laws~
1- An object moving at a constant velocity keeps moving at the velocity unless an unbalanced net force acts on it.
2- The acceleration of an object is in the same direction as the net force on the object.
3-When one object exerts a force on a second object, the second one exerts a force on the fist that is equal in strength and opposite in direction.

Newton's First law states that an object remains at rest or in motion with a constant velocity unless acted upon by an external force. Newton's Second Law says that the acceleration of an object is in the same direction as the net force on the object, and that the acceleration can be calculated from the equation of acceleration=netforce over mass. Newton's Third Law is that to every action there is an equal and opposite reaction.

Newton's third law of motion describes when one object exerts a force on a second object, the second one exerts a force on the first that is equal in strength and opposite in direction.

First law is states an object at rest remains at rest and an object in motion continues in motion with constant velocity unless experiences external force that stops it.
the second the acceleration of an object is directly proportional to the net force and the objects mass.The Third for every action, there is an equal and opposite reaction.

An object at rest remains at rest and an object in motion continues in motion.

The acceleration of an object is proportional to the net forceand inverselyto an objct.

For every actoin there is an equal and opposite reaction.

1. An object moving at a constant velocity keeps moving at that velocity unless an unbalanced net force acts on it. If an object is at rest, it stays at rest unless an unbalanced net force acts on it.

2. The acceleration of an object is in teh same direction as the net force on the object, and that the acceleration can be calculated from the equation: a=Fnet/m

3. When one object exerts a force on a second onbect, the second one exerts a force on the first that is equal in strength and opposite in direction. "To every acton force there is an equal and oppostie reaction force"

pauly said...

The first law is when an object at rest stays at rest unless acted upon by a outside sources.
The second law is acceleration of an object is in the same direction as the net force on the object.
The third law is motion is when one object exerts a force on a second object, the second exerts a force on the first that is equal in strength to the opposite in direction

1. An object at rest remains at rest and an object in motion continues in motion with constant velocity unless experiences a net external force.

2. The acceleration of an object is directly proportional to the net force and inversely proportional to objects mass.

3. For every action, there is an equal but opposite reaction.
