Discipline 2 Physical Science
Standard: Force and Motion
K-7 Standard P.FM: Develop an understanding that the position and/or motion of an object is relative to a point of reference. Understand forces affect the motion and speed of an object and that the net force on an object is the total of all of the forces acting on it. Understand the Earth pulls down on objects with a force called gravity. Develop an understanding that some forces are in direct contact with objects, while other forces are not in direct contact with objects.
P.FM.E.1 Position- A position of an object can be described by locating the object relative to other objects or a background. The description of the motion of an object from one observer's view may be different from that reported from a different observer's view.
P.FM.00.11 Compare the position of an object (for example: above, below, in front of, behind, on) in relation to other objects around it. 
P.FM.00.12 Describe the motion of an object (for example: away from or closer to) from different observers' views.
P.FM.E.2 Gravity- Earth pulls down on all objects with a force called gravity. With very few exceptions, objects fall to the ground no matter where the object is on the Earth. 
P.FM.00.21 Observe how objects fall toward the earth. 
P.FM.03.22 Identify the force that pulls objects towards the Earth.
P.FM.E.3 Force- A force is either a push or a pull. The motion of objects can be changed by forces. The size of the change is related to the size of the force. The change is also related to the weight (mass) of the object on which the force is being exerted. When an object does not move in response to a force, it is because another force is being applied by the environment. 
P.FM.00.31 Demonstrate pushes and pulls.
P.FM.00.32 Observe that objects initially at rest will move in the direction of the push or pull.
P.FM.00.33 Observe how pushes and pulls can change the speed or direction of moving objects. 
P.FM.00.34 Observe how shape (for example: cone, cylinder, sphere), size, and weight of an object can affect motion. 
P.FM.03.35 Describe how a push or a pull is a force.
P.FM.03.36 Relate a change in motion of an object to the force that caused the change of motion. 
P.FM.03.37 Demonstrate how the change in motion of an object is related to the strength of the force acting upon the object and to the mass of the object. 
P.FM.03.38 Demonstrate when an object does not move in response to a force, it is because another force is acting on it.
P.FM.E.4 Speed- An object is in motion when its position is changing. The speed of an object is defined by how far it travels divided by the amount of time it took to travel that far.
P.FM.03.41 Compare and contrast the motion of objects in terms of direction.
P.FM.03.42 Identify changes in motion (change direction, speeding up, slowing down). 
P.FM.03.43 Calculate the speed of an object based on the distance it travels divided by the amount of time it took to travel that distance. 
P.FM.M.2 Force Interactions- Some forces between objects act when the objects are in direct contact (touching), such as friction and air resistance, or when they are not in direct contact (not touching), such as magnetic force, electrical force, and gravitational force. 
P.FM.05.21 Distinguish between contact forces and non-contact forces. 
P.FM.05.22 Demonstrate contact and non-contact forces to change the motion of an object. 
P.FM.M.3 Force- Forces have a magnitude and direction. Forces can be added. The net force on an object is the sum of all of the forces acting on the object. The speed and/or direction of motion of an object changes when a non-zero net force is applied to it. A balanced force on an object does not change the motion of the object (the object either remains at rest or continues to move at a constant speed in a straight line).
P.FM.05.31 Describe what happens when two forces act on an object in the same or opposing directions. 
P.FM.05.32 Describe how constant motion is the result of balanced (zero net) forces.
P.FM.05.33 Describe how changes in the motion of objects are caused by a non-zero net (unbalanced) force.
P.FM.05.34 Relate the size of change in motion to the strength of unbalanced forces and the mass of the object.
P.FM.M.4 Speed- Motion can be described by a change in position relative to a point of reference. The motion of an object can be described by its speed and the direction it is moving. The position and speed of an object can be measured and graphed as a function of time.
P.FM.05.41 Explain the motion of an object relative to its point of reference.
P.FM.05.42 Describe the motion of an object in terms of distance, time and direction, as the object moves, and in relationship to other objects.
P.FM.05.43 Illustrate how motion can be measured and represented on a graph.
