NEWTON’S LAWS WORKSHEET – KEY I. NEWTON’S FIRST LAW OF MOTION 1. Newton’s ﬁrst law of mo2on is also known as the LAW OF INERTIA 2. Newton’s ﬁrst law says that a. an object that IS NOT MOVING, or is at AT REST will stay at AT REST AND b. an object that IS MOVING will keep moving with constant VELOCITY which means at the same SPEED and

Second Law. To apply Newton‘s Second Law we draw a free­body diagram (FBD). Since the person has mass, he has weight. Since the person touches the floor of the elevator, there is a normal force from the floor. We will assume that the person will accelerate upwards. Applying Newton‘s Second Law yields, Fy = may

### Newton S First Law Worksheet SOLUTIONS

Newton’s First Law Worksheet SOLUTIONS 1. Fully and clearly state Newton’s 1st law. An object in motion at a constant velocity (or at rest) will remain in motion at a constant velocity (or at rest) unless acted upon by an unbalanced, external force. 2. An object is at rest. What does the object have that tends to keep it at rest?

### Newton S Laws Worksheets With Answers

In general, simply write Newton’s second law in components along the different directions. Then you have the following equations: ∑Fx=max,∑Fy=may.∑Fx=max,∑Fy=may. (If the system accelerates horizontally .B, you can set ay=0.ay=0.) We need this information to identify unknown forces that affect a system. As always, we need to look at the solution.
