True or false: 1) If a net force acts on an object, the object's speed will...
i) _________ True or False. A force with a strength of 50 Newtons acts on two different objects: a car and a truck. Because the force on the truck is the same as the force on the car, both vehicles will experience the same acceleration. Explain your reasoning. ii) Give an example of rotational motion. iii) When the net torque on an object is zero, the object will a) continue to spin in the same direction (clockwise or counterclockwise) b)...

An object subject to a net force cannot have a constant speed . __________ An object moving at a constant rate cannot have one force acting on it. __________ An object that has a constant speed in one direction has no forces acting on it. __________ Free-body diagrams always tell us the direction of motion. __________ When the net force on an object is zero the object is at rest. __________ The sum of the Newton’s...
If a force always acts perpendicular to an object's direction of motion, that force cannot change the object's kinetic energy. True or False. Why?
Does a force exerted on an object always increase the object's speed? If yes, explain why. If no, provide an example in which an external force does not increase an object's speed.

The z-component of a vector can be (+), (-), or zero A True B false if A is perpendicular to B, then B middot A = 0 A True B False The x-component of a vector can be (+), (-), or zero A True B False The scalar (or dot) product of two vectors can be (+), (-) or zero A True B False If A = B times C and C = 16j, then Ay = 0 A...
Answer the following questions. Choices: True, False. A. During the collision of a car with a large truck, the truck exerts an equal size force on the car as the car exerts on the truck. B. During the collision of a car with a large truck, the car exerts a lesser force on the truck than the truck exerts on the car. C. In order not to slow down, an object moving at a constant velocity needs a non-zero net...
