Acceleration is a very important concept in physics and forms an integral part of the MDCAT Quiz preparation for both medical and dental students. It basically means how the velocity of an object is changing with time. Acceleration is a vector quantity, and hence, it has magnitude as well as direction. Whether speeding up, slowing down, or changing direction, understanding acceleration goes a long way in solving a variety of motion-related problems in the MDCAT exam. Mastering this topic will help one have more confidence when approaching questions based on velocity, displacement, and forces.
Understanding Acceleration in Motion
Acceleration may be defined mathematically as the change in velocity divided by the time taken for that change. It can occur in different scenarios, either uniform acceleration, where the rate of change of velocity is constant, or non-uniform acceleration, where the rate of change of velocity varies. Common examples of accelerated motion include a car speeding up on a highway or an object in free fall.
MDCAT Quiz: Acceleration Questions
In the MDCAT Quiz, there are questions in which students are asked to calculate acceleration in various situations. Mostly, these questions involve objects moving with uniform or variable acceleration; therefore, one must be careful in applying the appropriate equations of motion, depending upon the information given. For example, questions may ask for the calculation of an object’s acceleration under the influence of gravity or the acceleration of a vehicle. Therefore, practice in the MDCAT Quiz on acceleration will bring perfection in attempting and solving problems related to acceleration in the real world of physics.
