An object travels along a straight, horizontal surface with an initial speed of 2 . The velocity of the object as a function of time is given in the table above. Which of the following graphs represents the object's acceleration as a function of time?

To run the physics cart, the fan speed of the cart is manipulated. this is the (blank) variable. the cart accelerates due to the speed of the fan. acceleration is therefore the (blank) variable. a “constant” is a parameter that stays the same regardless of the variables. one parameter of the cart that is held constant is the (blank) .

All the simple machines make work easier to do by changing the or of a force. a. size; type b. work; type c. size; direction d. type; direction
