Do Now: Is it possible to make race cars even faster? ( 5 minutes)

               Does Mass Matter?

Directions:  The goal of this activity is to determine how the mass of an object impacts the acceleration when a constant force is exerted on the object. 

Procedure: Using a simulation of a spring scale, students  will pull a cart along a path measured. The simulation will give you the measure of time each second. There will be two different trials run. The force is going to be 2N. Trial 1 will use a cart with 5 Kg; Trial 2 will use a cart with 10 Kg.

You will now calculate the acceleration for the firts trial.
Acceleration can be calculated by dividing the force applied to the object (in Newtons) by the mass of the object (in kilograms). Use the force and mass you recorded to calculate the rate of acceleration for each trial. The formula is f=ma a=f/m

You will now calculate the acceleration for the second trial.
Acceleration can be calculated by dividing the force applied to the object (in Newtons) by the mass of the object (in kilograms). Use the force and mass you recorded to calculate the rate of acceleration for each trial. The formula is f=ma a=f/m

Newton’s second law of motion states that the amount of force exerted on an object is directly related to the mass and acceleration of that object.

This can also be rearranged to state that the acceleration of an object can be impacted by the mass and the force exerted on that object.

In this demonstration, the force was kept constant, while the mass of the object was increased.

Using the calculated data in question 11 and 12, Create a bar graph comparing the acceleration and mass in each trial.

The formula used to support Newton’s second law of motion is force = mass * acceleration (f = ma). 

Using the information in this demonstration, write a scientific claim for the relationship of mass and acceleration on an object when the force is held constant.
