Explain what allows the object to accelerate? A force applied to any object at rest causes it to accelerate in the direction of the force applied. 2. What is the difference between speed and velocity of the object? Speed is how fast an object is moving. Velocity is the rate at which an object changes position in a certain direction. Velocity deals with direction, while speed does not. 3. Define “instantaneous velocity” Instantaneous velocity is the velocity of an object in motion at a specific point in time. 4. Is it possible to know the instantaneous velocity of an object? Why? Instantaneous velocity is the limit of velocity as the change in time approaches zero, which is equivalent to the derivative of position with respect to time. Instantaneous velocity can be measured because it is like average velocity, but instead to measure it directly you narrow the period of time so that it approaches zero. 5. Define the terms positive acceleration and negative acceleration . Positive acceleration is the change in velocity of an object in the positive direction, as defined for the given time, and negative acceleration is acceleration directed towards the direction that is defined as the negative direction. The positive direction is usually going forward, and the negative direction is usually going backwards.

The acceleration of an object when the height is manipulated varies in time. When the height is higher the result acceleration will be faster as compared with that of a lower height. With a lower height the acceleration of an object will then be slower compared with that of a higher height.

### What students are saying

• As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

• I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

• The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
