You do . work. any time you exert a force on an object that causes the object to move in the same direction as the force. . In addition, the force you exert must be . in the same direction. as the object’s motion. . Objective: I will . identify the same value relating the measures of x and the measures of y in a proportional relationship as the constant of proportionality and recognize it as the unit rate in the context of a given situation. . No, because its speed is constant.. Yes.. Not enough information is given.. A car rounds a circle while maintaining a constant speed. Which arrow represents the direction of the net force on the car as it rounds the curve at the instant shown above? . Work is done when:. A . force . is exerted on an object.
