Human Dynamics Cart

Let your students become a part of the experiment!

Active involvement turns into fun physics!  The Human Dynamics Cart allows students to become part of the demonstration or experiment.  Here are a few fun ways you can use it? 

• Demonstrate Newton’s 2^nd Law – on one cart place a large student, and on the second cart a smaller student.  If equal forces are applied, the smaller student will undergo a larger acceleration. 
• Demonstrate Newton’s 3^rd Law – keep the two students on the cart and have them face each other.  Have one student push gently on the other student.  Due to the equal and opposite forces being applied, both students move in opposite directions. 
• Create an inelastic collision – have a student sit on the cart and toss them a heavy object such as a sand bag or a medicine ball.  After the student catches the object, the cart will move in the direction of the toss.  Do it in reverse – Have the student sit with the heavy object on the cart.  If this student throws the object off the cart it will recoil in the opposite direction.
