- Which of the following are true statements about velocity, acceleration, and force? (More than one answer) A All three of these quantities are vectors. B Force always causes velocity to increase. C Acceleration always causes velocity to increase. D Acceleration is a change in force per unit time. E Force and acceleration are related by a law of nature; acceleration and change in velocity are related by a definition. F Velocity is not a vector, but force and acceleration are vectors. G Force = mass times velocity H Acceleration and net force are always in the same direction, but velocity can be in any relative direction to those. I Force and acceleration are related via mass. J Newton's Second Law of Motion says that: acceleration = mass times force5. Two 20kg carts are attached to opposite ends of a cable. Each cart is on a different side of an incline as shown.

- In the image is a stopper attached to a fishing line that is threaded theough a glass rod. Hanging from the end of the line opposite the stopper is a 100-gram mass. The stopper is being whirled in a horizontal circle, first quickly, then decreasing to a slower speed. a. True or false: the only outward forces are the force of the stopper pulling on the string, and the string pulling on the glass rod. b. Does there appear to be a relationship between the speed and the force needed to keep the stopper moving in a circular path? If so, what kind of relationship do you expect? As the speed increases, does the force needed increase or decrease? Is this some type of direct relationship or an inverse relationship? c. Does there appear to be a relationship between the radius of the circulat motion and the force needed to keep the stopper moving in a circular path? If so, what kind of relationship do you expect? As the radius increases, does the force needed incrase or decrease? Is this some…Decont M ts. Using Newton's second law to calculate the acceleration of a key hanging in a car. You tape one end of a piece of string to the ceiling light of your car and hang a key with mass m on the other end of the string, A protractor taped to the light allows you to the angle the string makes with the vertical. Your friend drives the car while you make measurements. When the car has a constant acceleration with magnitude a toward the right, the string hangs at rest (relative to the car), making an angle ß with the vertical. (a) Derive an expression for the acceleration a in terms of the mass m and the measured angle B. (b) In particular, what is a when B = 45°? When B=0? Show your work that leads to your answer. Explain each step in your work to get the full credit. The equation with no ts. Calculate the magnitude and explanation will get your answer zero point.
