Physics 310 Experiment 6 Newton’s Second Law DATA SHEET Name: _________________ Date: ___________ Prediction 1. What happens to an object when you apply a net force to it? When you apply a net force to an object it accelerates in the direction of the net force. 2. What happens to the motion of an object if it has a constant mass but you change the magnitude of the net force on it? If you change the magnitude of the net force on an object it will accelerate proportion to the net force, and will either increase or decrease. 3. Paste the velocity-time graph of your data showing the four fits 4. Data Table 1 Item Mass (kg) Run #1: Total mass of cart, paper clip and one 0.109 Phys310 Lab Page 1 Experiment 6
