Question

iv. everyday examples
1 sports: a football player pushes another player. the ______ player will move faster when pushed with the same force.

1. vehicles: a truck and a car moving with the same force. the truck will accelerate more ______ because its heavier.

v. applying newtons second law

1. pulling a wagon: more people (mass) require more ______ (force) to move.
2. tug - of - war: more people on one side apply more ______ to win.

vi. connection to previous activities
think about how newtons second law relates to activities we did earlier this week:

1. _________________________
2. _________________________

vii. reflection question
how can you apply more force or reduce mass to make something move faster in real life?

Explanation:

All questions are based on Newton's Second Law, which states $F = ma$ (force equals mass times acceleration), or rearranged as $a = \frac{F}{m}$ (acceleration is inversely proportional to mass for constant force).

1. IV.1: For equal force, lower mass means higher acceleration (faster movement).
2. IV.2: For equal force, higher mass means lower acceleration.
3. V.1: To keep acceleration constant, more mass needs more force.
4. V.2: More people on a tug-of-war side create greater force to overcome the other side.
5. VI.1 & 2: Connect to activities where mass/force affected acceleration (e.g., moving heavy vs. light objects, pulling with more/less effort).
6. VII: Real-life applications use $a = \frac{F}{m}$ to increase speed.

Answer:

IV. Everyday Examples

1. lighter
2. slowly

V. Applying Newton's Second Law

1. force
2. force

VI. Connection to Previous Activities

1. Example: When we pushed a light box and a heavy box with the same effort, the light box sped up faster (lower mass = higher acceleration for same force).
2. Example: When we pulled a wagon with just one person vs. three people, we had to pull harder (apply more force) to get the heavier wagon moving at the same speed.

VII. Reflection Question
Example: To make a bicycle move faster, you can either push harder on the pedals (apply more force) or remove heavy items from the bike (reduce mass) so the same amount of force creates more acceleration.
