Question

Answer question no. 4.1-4.4on the basis of your understanding of the following paragraph and the related studied concept: By observing the motion of objects on an inclined plane Galileo deduced that objects move with a constant speed when no force acts on them. He observed that when a marble rolls down an inclined plane, its velocity increases. It thus suggests that an unbalanced (external) force is required to change the motion of the marble but no net force is needed to sustain the uniform motion of the marble. 4.1)State Newton’s 1st law of motion? 1 4.2)Why is it called the law of inertia? 1 4.3)Define inertia? 1 4.4)On what factors does inertia depend?

Answer 1

Explanation:

When that happens they no longer accelerate but move at a constant speed, called the terminal velocity. The time it takes for objects falling ...

Answer 2

Answer:

due to terminal velocity it occurs
