7.1: Forces & Motion 3 Dimensions & Progressions

Unit 1

● I can provide evidence that the change in an object’s motion depends on the sum of the forces on the object and the mass of the object.

● Students will bowl with objects of different masses to demonstrate that the motion or

● I can provide evidence that the change in an object’s motion depends on the sum of the forces on the object and the mass of the object.

● Students explore the
