Force and Velocity Concepts

The class begins with attendance and an introduction to lesson 1.4, focusing on force and velocity. Students engage in a warm-up activity with the Sherman story comic to differentiate between force and velocity. The lesson continues with a baseball activity to explore the cause and effect relationship between force and velocity. A hands-on activity using spring launchers helps students understand how different forces affect velocity. Students watch a video and answer questions on Amplify. The session concludes with a review of the investigation results and homework instructions.

What is the main focus of today's lesson?

• Reviewing attendance procedures

• Discussing key vocabulary words

• Learning about digital notebooks

• Explaining the relationship between force and velocity

How can force and velocity be differentiated?

• Velocity is the strength of an object

• Force causes an object to move, while velocity is the speed and direction of that movement

• Force is the result of velocity

• Velocity is the cause of force

What happens to a baseball when it is hit by a bat?

• It stops moving

• It changes direction due to the force applied by the bat

• It loses velocity

• It moves in the same direction as before

What vocabulary words are used to explain the baseball's change in direction?

• Speed, distance, time

• Force, velocity, cause, effect

• Mass, weight, gravity

• Friction, inertia, momentum

What is the purpose of using spring launchers in the hands-on activity?

• To test the durability of jar lids

• To measure the weight of jar lids

• To exert different forces on jar lids and observe changes in velocity

• To calculate the distance traveled by jar lids

What is the independent variable in the spring launcher activity?

• The force applied by the spring launcher

• The distance the jar lid travels

• The time taken for the jar lid to reach the end

• The type of jar lid used

Why is it important to conduct multiple trials in the experiment?

• To make the experiment more interesting

• To use up all the jar lids

• To verify the consistency and accuracy of results

• To ensure the spring launcher is working

What was observed about the jar lid with force three in the trials?

• It reached the end of the meter stick first in all trials

• It moved in the opposite direction

• It moved slower than the others

• It did not move at all

What should students do after completing the hands-on activity?

• Start a new experiment

• Submit their answers on Pear Deck

• Watch another video

• Discuss their results with a partner

What additional task is assigned for homework?

• Write an essay on force

• Complete a reading on friction

• Solve math problems related to speed

• Create a presentation on velocity
