This is a short activity that will help students to understand Newton's 2nd Law of Motion.
This activity aligns with NGSS DCI MS-PS2A
Students will use 3 different balls with different mass to see how mass affects acceleration.
Students should have some background information about friction and gravity prior to completing this activity. You will also need 1 tennis ball, 1 ping-pong ball and 1 golf ball per group. (You may be able to sub these out for other types of balls.)
