... Why Isn’t Work Done On The Bucket of Water? • Work is only done when COMPONENTS of a force are parallel to a displacement. • Since Kim exerts an upward force on the bucket of water, which is perpendicular to the displacement, there is no work done on the bucket of water. ...

Inertial and Non-Inertial Frames of Reference - K
... Your new weight in this accelerated, non-inertial reference frame is called the ‘apparent weight’. On a roller coaster, when you are in free fall down a large hill, the acceleration of the ride is equal to g (9.81 m/s2) and the normal force between you and your seat becomes zero. This makes your app ...

... from an object, then the motion of that object would not change. This was Newton's first law of motion. In our study of motion, we need to start clarifying the concept of mass. In effect, we will find that mass is a measure of how hard it is to get an object moving. Applying a force to a light obje ...

... • What does Newton’s 1st Law of motion state? – An object at rest will remain at rest and an object in motion will remain in motion, unless acted upon by an unbalanced force. • Why is Newton’s 1st law of motion sometimes called the law of intertia? – Inertia is a measure of an object’s tendency to r ...
