Answer:
Applications of first law of motion:
1.Newton’s laws of motion can be applied in numerous situations to solve motion problems. Some problems contain multiple force vectors acting in different directions on an object.
2. Some motion problems contain several physical quantities, such as forces, acceleration, velocity, or position. You can apply concepts from kinematics and dynamics to solve these.
Answer and Explanation:
What is Newton’s First Law of Motion?
Newton’s first law states that a body remains in the state of rest or uniform motion in a straight line unless and until an external force acts on it.
Putting Newton’s 1st law of motion in simple words, a body will not start moving until and unless an external force acts on it. Once it is set in motion, it will not stop or change its velocity until and unless some force acts upon it once more. The first law of motion is sometimes also known as the law of inertia.
There are two conditions on which the 1st law of motion is dependent:
Objects at rest: When an object is at rest velocity (v= 0) and acceleration (a = 0) are zero. Therefore, the object continues to be at rest.
Objects in motion: When an object is in motion, velocity is not equal to zero (v ≠ 0) while acceleration (a = 0) is equal to zero. Therefore, the object will continue to be in motion with constant velocity and in the same direction.
