Define problems related to the effects of friction and design possible solutions to reduce the effects on the motion of an object.
- Physical Science: Exploring Pushes and Pulls
The student will demonstrate an understanding of the effects of pushes, pulls, and friction on the motion of objects.
An object that is not moving will only move if it is pushed or pulled. Pushes and pulls can vary in strength and direction and can affect the motion of an object. Gravity is a pull that makes objects fall to the ground. Friction is produced when two objects come in contact with each other and can be reduced if needed.
