View question - A constant force applied to object A causes it to accelerate at 5 m/s2 .The same force applied to object B causes an acceleration of 3 m/s2
- This interactive activity demonstrates how vectors are used to represent velocity (speed and direction) and acceleration. In the activity, vectors change in real-time as you "drive" a car on a flat plain; as you change speed and direction, vectors originating from the car respond to your actions. A graph depicting speed vs. time also responds to your actions, displaying both the speed and ...
Solutions to the problems on velocity and uniform acceleration are presented along with their solutions. Problem 12: A car accelerates from rest at 1.0 m/s 2 for 20.0 seconds along a straight road . It then moves at a constant speed for half an hour.
- Answer to Essential Question 2.7: A common misconception is that the ball's acceleration is zero at the maximum-height point. Consider one more example of applying the general method for solving a constant-acceleration problem. EXAMPLE 2.8 - Combining constant-acceleration motion and...
Furthermore, in many other situations we can accurately describe motion by assuming a constant acceleration equal to the average acceleration for that motion. Finally, in motions where acceleration changes drastically, such as a car accelerating to top speed and then braking to a stop, the motion can be considered in separate parts, each of ...
- Uniform, or constant, acceleration is a type of motion in which the velocity of an object changes equal amounts in equal time periods.

Car Revs High But No Acceleration
- Practice Problems: Speed, Velocity, and Acceleration A proper answer must include a direction as well. This is quite easy to do. Since the car is starting from rest and moving forward, its acceleration must also be forward. The ultimate, complete answer to this problem is the car is accelerating at… a = 4.06 m/s 2 forward.
Which of the following simplifying assumptions is it reasonable to make in this problem? A. During each of the three different stages of its motion, the car is moving with constant acceleration. B. During each of the three different stages of its motion, the car is moving with constant velocity. C. The highway is straight (i.e., there are no ...
- Support your answer with reasoning. Acceleration: Y/N Dir'n a. Reason: The spacing between consecutive positions is constant; this indicates a constant speed and no acceleration. No --b. Yes Reason: The spacing between consecutive positions is increasing; this indicates a speeding up motion and thus, an acceleration. An object that is
If you think that none of the graphs represents the correct answer, choose J. The cart moves toward the right (away from the origin) with a steady velocity. The cart moves toward the right and is speeding up at a steady rate (constant acceleration). The cart moves toward the left (toward the origin) with a steady (constant) velocity.
