MO.2. Properties and Principals of Force and Motion
2.1. The motion of an object is described by its change in position relative to another object or point
2.1.A. The motion of an object is described as a change in position, direction, and speed relative to another object (frame of reference)
2.1.A.b. Scope and Sequence - Force, Motion, and Work: Classify different types of motion (e.g., straight line, projectile, circular, vibrational)
2.2. Forces affect motion
2.2.A. Forces are classified as either contact (pushes, pulls, friction, buoyancy) or non-contact forces (gravity, magnetism), that can be described in terms of direction and magnitude
2.2.A.a. Scope and Sequence - Force, Motion, and Work: Identify and describe the types of forces acting on an object in motion, at rest, floating/sinking (i.e., type of force, direction, amount of force in Newtons)
2.2.A.b. Scope and Sequence - Force, Motion, and Work: Compare the forces acting on an object by using a spring scale to measure them to the nearest Newton
2.2.D. Newton's Laws of Motion explain the interaction of mass and forces, and are used to predict changes in motion
2.2.D.b. Scope and Sequence - Force, Motion, and Work: Explain that when forces (including magnetic, gravity, friction, push or pull) are balanced, objects are at rest or their motion remains constant
2.2.D.c. Scope and Sequence - Force, Motion, and Work: Explain that a change in motion is the result of an unbalanced force acting upon an object
2.2.D.d. Scope and Sequence - Force, Motion, and Work: Explain how the acceleration of a moving object is affected by the amount of net force applied and the mass of the object
