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
