1st Law Inertia is the tendency of an object to resist changes in its velocity: whether in motion or motionless. These pumpkins will not move unless acted on by an unbalanced force. 11
Define in a sentence Galileo's Law of Inertia (Alias-Newton's first Law of Motion) 4. Describe what effects an object's inertia. 5. Characterize rotational inertia. (a) Describe the relationship between an objects rate of spin and the object's distribution of it's mass. 6. Give examples of how inertia is demonstrated in everyday life (TOYS) 7.
Inertia is the tendency for an object at rest to remain at rest, or for a moving object to remain in motion in a straight line with constant speed. This key property of objects was first described by Galileo. Later, Newton incorporated the concept of inertia into his first law, which is often referred to as the law of inertia.
1.2.1 Inertial Frames of Reference. The concept of an inertial frame of reference is central to the application of Newton’s Laws. An inertial frame is one that is in a uniform and non-accelerating state of motion. In fact, Newton’s Laws are only applicable to such frame of references.
Moment of inertia is the property of a deformable body that determines the moment needed to obtain a desired curvature about an axis. Moment of inertia depends on the shape of the body and may be different around different axes of rotation. Moment-curvature relation: E: Elasticity modulus (characterizes stiffness of the deformable body) : curvature
Step 3: Introduce a coordinate system, the inertial frame, and write the equations of motion. Step 4 : Motion of a body may be constrained to move along certain path or plane.
Define mass and inertia. Understand Newton's first law of motion. Experience suggests that an object at rest will remain at rest if left alone, and that an object in motion tends to slow down and stop unless some effort is made to keep it moving. What Newton’s first law of motion states, however, is the following:
