# Unit 7 Force and Motion

Teacher Brittnee Zeak Science 5 22-24 Force and Motion
Standard(s) Taught

SC.5.P.13.1 – Identify familiar forces that cause objects to move, such as pushes or pulls, including gravity acting on falling objects.

SC.5.P.13.2 – Investigate and describe that the greater the force applied to it, the greater the change in motion of a given object.

SC.5.P.13.4 – Investigate and explain that when a force is applied to an object but it does not move, it is because another opposing force is being applied by something in the environment so that the forces are balanced.

SC.5.P.13.3 – Investigate and describe that the more mass an object has, the less effect a given force will have on the object’s motion.

Learning Targets and Learning Criteria

SC.5.P.13.1 – Students will:

• review that gravity is a force that can be overcome.
• review examples of magnetic attraction and repulsion.
• identify familiar forces (pushes, pulls, friction, gravity, magnetism) that cause or hinder movement of objects
• identify two or more forces acting upon an object in a scenario
• interpret the effect of two or more forces acting upon an object
• recognize that friction is a force that resists movement.

SC.5.P.13.2 & SC.5.P.13.4 – Students will:

• measure force in Newtons (N) using a spring scale. demonstrate that a force may change an object’s original position.
• investigate that the greater the force applied to an object, the greater the change in motion of a given object.
• the amount of force applied to an object affects the speed and/or distance at which it moves o force affects the direction an object moves
• investigate and explain the effect balanced and unbalanced forces have on motion.
• balanced forces are present when an object does not move because opposing forces are holding the object in place (e.g., a book laying on a table is being acted upon by the table pushing up on the book from below and gravity pushing down from above).
• unbalanced forces are present when an object does move because one of the opposing forces moves the object from its original position.

SC.5.P.13.3 – Students will:

•  investigate and describe the relationship among mass, force, and motion.
• objects with greater mass require more force to move compared with objects of less mass (and the reverse).
• more force is required to slow down an object in motion with greater mass compared to an object with less mass (and the reverse).
