Newton's Laws Day 1
Newton's First Law
Today we discuss Inertia.
Here is what you can expect to be asked to do on the Physics state test:
STANDARD I: Students will understand how to measure, calculate, and describe the motion of an object in terms of position, time, velocity, and acceleration.
Objective 4: Use Newton's first law to explain the motion of an object.
a. Describe the motion of a moving object on which balanced forces are acting.
b. Describe the motion of a stationary object on which balanced forces are acting.
c. Describe the balanced forces acting on a moving object commonly encountered (e.g., forces acting on an automobile moving at constant velocity, forces that maintain a body in an upright position while walking).
STANDARD II: Students will understand the relation between force, mass, and acceleration.
Objective 1: Analyze forces acting on an object.
a. Observe and describe forces encountered in everyday life (e.g., braking of an automobile - friction, falling rain drops - gravity, directional compass - magnetic, bathroom scale - elastic or spring).
b. Use vector diagrams to represent the forces acting on an object.
c. Measure the forces on an object using appropriate tools.
d. Calculate the net force acting on an object.
