📚 Topic Summary
In science, a force is any interaction that, when unopposed, will change the motion of an object. A force can cause an object with mass to change its velocity (which includes to begin moving from a state of rest), i.e., to accelerate. Forces can be described as either a push or a pull. A push moves an object away, while a pull brings an object closer. Understanding these basic forces helps us explain how things move around us!
Let's explore pushes and pulls with some fun activities!
🧲 Part A: Vocabulary
Match the terms with their definitions:
- Term: Force
- Term: Push
- Term: Pull
- Term: Gravity
- Term: Friction
Definitions:
- A force that resists motion when two surfaces are in contact.
- An interaction that, when unopposed, will change the motion of an object.
- To move something away from yourself.
- To move something toward yourself.
- A force that attracts objects with mass towards each other.
(Match the terms above with these definitions.)
✍️ Part B: Fill in the Blanks
Complete the sentences using the words: push, pull, force, gravity, and friction.
When you open a door, you either apply a ______ or a ______. ______ is a fundamental interaction that causes objects to be drawn together. A ______ is any interaction that can change an object's motion. ______ opposes motion between surfaces in contact.
🤔 Part C: Critical Thinking
Give real-world examples of a push and a pull. Explain how these actions affect the motion of the object.
