What relationship do you observe between force and distance
Independent Practice:
Directional forces:
Using your knowledge that forces can change the speed or direction an object is moving answer the following questions below.
An object is hit with a force shown by the arrow, identify the direction the object will travel, or if it will speed up or slow down. Circle the best response

Why did the jar lid move different distances and velocities when the distance the spring launcher was pulled back changed?
CFS:
Accurately identifies applied forces by analyzing the movement of objects
Accurately describes how changing independent variables (force) impact the outcomes in testing
