FM: Lesson 1.6 (9/9) Version B - Alex Kovalik (he/him/his) | Library

Objective: SWBAT construct a visual and written scientific explanation in order to explain the cause and effect relationship between force strength and velocity change.

Match the following vocabulary terms with the correct definition:

Draggable item		Corresponding Item
Velocity		a push or a pull that can change the motion of an object
Friction		speed in a particular direction
Force		a force between an object and the surface it is moving over

If you applied the same amount of force to a basketball and a beachball what would result in a faster velocity?

Guided Notes: Energy

Model the force diagram below

0

If the Pod is moving the right with a force of 200N, what force would need to be applied by the thrusters for the object to come to a complete stop?

0

If the Pod is moving the right with a force of 200N and the pod were to bounce off the space station, what amount of force might cause this?

0

Practice:

0

If the space pod had a mass of 100kg and the thrusters applied 10N too much or too little force, what was the acceleration of the space pod towards or away from the space station?,

Force-Velocity Models allow scientists to visualize and analyze the changes of direction and velocity by forces.

2

What is the relationship between the amount of force applied to a moving object and the direction of its motion after contact?
CFS:
Accurately identifies changes in the dependent variable by analyzing the movement of objects
Accurately describes the relationship between force, mass, and acceleration
"The amount of force I apply to an object impacts its direction because ..."

Exit Ticket:

Model and explain the events that would cause these changes in velocity. For each claim, describe the thruster force and how that would result in the pod moving away from the station.

Claim 1: The thrusters caused the pod to move in the opposite direction.

1

Draw an arrow in the middle column to indicate the direction and amount of force causing the change in velocity.

Claim 2: The thrusters only slowed the pod, it didn’t stop; the pod hit the space station, which made it bounce and move in the opposite direction.

1

Draw an arrow in the middle column to indicate the direction and amount of force causing the change in velocity.

2

Based on your understanding of force, why do you think the pod changed direction in Claim 1, but only slowed down in Claim 2?
CFS:
Accurately identifies changes in the dependent variable by analyzing the movement of objects
Accurately describes the relationship between force, mass, and acceleration

"I think the pod changed direction in Claim 1 and only slowed down in claim 2 because ... "
