(a) A fundamental law of motion states that the acceleration of an object is directly proportional to the resultant force exerted on the object and inversely proportional to its mass. If the proportionality constant is defined to have no dimensions, determine the dimensions of force. (Use the following as necessary: M, L, and T.)

(b) The newton is the SI unit of force. According to the results for (a), how can you express a force having units of newtons using the fundamental units of mass, length, and time? (Use the following units as necessary: kg, m, and s.)

Solutions

Expert Solution

This problem can be solved using basic dimensional analysis. The dimension of force comes out as [MLT-2] and Newton can be expressed using fundamental units as kg m s-2. Detailed explanation given below. Ask me if you have any doubts. Feedback will be helpful.
