Science Standard IV, Physics
Lesson 400, Introduction to Physics
Defining force, speed, velocity, acceleration, and deceleration
Defining and understanding Newton’s first law, the law of inertia
Identifying the units of measurement for velocity, acceleration, and deceleration
Calculating velocity and acceleration
Knowing Newton’s second law, F = m x a
Calculating force, acceleration, and mass
Calculating weight (m x 9.8 m/s2)
Understanding the differences between weight and mass
Describing vectors
Illustrating forces on an object with vectors
Understanding force of gravity and frictional force
Knowing Newton’s third law, that every action has an equal and opposite reaction
Knowing energy is fundamental to all scientific disciplines
Understanding how physics applies to biology, chemistry, earth science, and other sciences
Knowing what physics is, what techniques are appropriate to study it
Understanding how math relates to physics
Understanding that Earth’s internal & external energy sources are forces
Understanding that most observable forces can be traced to electrical forces acting between atoms & molecules
Recognizing the important role that mathematics serves when solving problems in physics
Understanding that any change in velocity is an acceleration
Understanding that acceleration due to gravitational force is proportional to mass and inversely proportional to the square of the distance between the objects
