2nd law of motion F=ma Force= mass x acceleration more mass=more force F= ma F= 2 kg times 2 m/s2 =4N F= 5 kg times 2 m/s2 = 10 N 10 N 5 kg 20 N 5 kg more acceleration = more force 1 kg X 10 m/s2 1 kg X 100 m/s2 Title: Newton’s 2nd Law of Motion Purpose: How does mass affect force? Hypothesis: Equipment: 1 toy car 6 washers balance 20 cm masking tape meterstick wooden ramp Procedure: 1. Set up a ramp using the wooden ramp . Place one end of the ramp on some books or against the wall. Tape the end of the ramp on the floor. 2. Measure the mass of the toy car. 3. Place the toy car at the top of the ramp. Let the car roll down the ramp. Do NOT add any additional force. Use a meter stick to measure how far the car rolled. Repeat this step for trials 2-5. DO NOT PUSH THE CAR! 4. Tape to washers to the toy car. Mass it. Repeat steps 2 and 3. 5. Tape 4 washers to the toy car and repeat. 6. Tape 6 washers to the toy car and repeat. Dependent variable: Independent variable: Constant variables: Quantitative Data Title: The Impact of Mass on Force Mass of car (g) Force of Car (measured by how far car travels in meters) Trial 1 0 washers Mass = ______ 2 washers Mass = ______ 4 washers Mass = ______ 6 washers Mass = ______ Trial 2 Trial 3 Trial 4 Trial 5 Average
