Question

Different masses are hung on a spring scale calibrated in newtons. The force exerted by gravity on 1.0 kg is shown in the image below in newtons. 9.8N What would be the force exerted by gravity on 6.5 kg? N9 09.8 N N9 N 96O

Answer 1

Given: for 1 kg, the reading is 9.8 N.

Therefore, For 6.5 kg.

Reading will be: F = (6.5 kg)(9.8) = 63.7 N = 64 N

Question (2) Answer:

• A ball rolls across a street and into a large soccer field.

According to Newton's First law of motion, Which states that “A body at rest or uniform motion will continue to be at rest or uniform motion until and unless a net external force acts on it”. Suppose a block is kept on the floor, it will remain at rest until we apply some external force to it. Also, we know that it takes us more effort or force to move a heavy mass. This is directly related to a property known as Inertia. This law is also known as the law of inertia.
