Define newton's all laws​

First Law

The first law states that an object at rest will stay at rest, and an object in motion will stay in motion unless acted on by a net external force. Mathematically, this is equivalent to saying that if the net force on an object is zero, then the velocity of the object is constant.

Second Law

The second law states that the rate of change of momentum of a body over time is directly proportional to the force applied, and occurs in the same direction as the applied force.

Third Law

The Third Law states that Every action has an equal an opposite reaction

1 law if our body is in rest it continues to be in rest unless some external forces applied to make it act in different ways

Explanation:

3rd law to every action there is equal and opposite reaction

sorry I don't know 2nd law

they should be similar or the same

graph slopes whilst gas cools, then it is flat whilst conensation to liquid happens, the coolong liquid then graphs as a slope when it solidifies graph is flat
