Question 1 Which of the following statement is not correct for an object moving along a straight path in an accelerated motion?

.

The Learning Objectives in this section will help your students master the following standards:. In addition, the High School Physics Laboratory Manual addresses content in this section in the lab titled: Position and Speed of an Object , as well as the following standards:. Ask for examples of both. Explain that deceleration is not used in physics because acceleration is either positive or negative. Lead students to their topics of interest, such as motor vehicles or sports. Explain that the capital Greek letter delta always means final minus initial and that the net change may be zero, positive, or negative. What does a vector arrow represent? Ask them to name some quantities that are vectors and some that are scalars.

When an object undergoes acceleration

In everyday conversation, to accelerate means to speed up. The accelerator in a car can in fact cause it to speed up. The greater the acceleration , the greater the change in velocity over a given time. The formal definition of acceleration is consistent with these notions, but more inclusive. Recall that velocity is a vector—it has both magnitude and direction. This means that a change in velocity can be a change in magnitude or speed , but it can also be a change in direction. For example, if a car turns a corner at constant speed, it is accelerating because its direction is changing. The quicker you turn, the greater the acceleration.

Reservation Criteria. The correct answer is Option 1. Exam Centres. The bandwidth of measurement is changed from 1 Hz to 10 Hz. Courses for Kids. So, option C is incorrect. Important Exams. Now we will observe each option carefully with the condition given in the problem, to check which one is correct. This question was previously asked in. So, option A is incorrect. It always falls towards the earth. Note- In contrast, instantaneous acceleration is measured over a short time interval. So, option D is incorrect. Additional Information Acceleration is a fundamental concept in physics that describes the rate of change of velocity with respect to time.

It mathematically gives the cause-and-effect relationship between force and changes in motion.

Acceleration can be positive or negative: Positive Acceleration : Speeding up in the positive direction. Which of the following decay processes is allowed? When an object undergoes acceleration then, its speed can increase or decrease or remain constant. Objects falling towards the earth is one example of acceleration because a gravitational force is experienced by the object due to its mass when it falls towards the earth. Assume that the noise spectral density, at any given frequency, in a current amplifier is independent of frequency. College Predictor. View Solution. Additional Information. JEE Advanced Result. Courses for Kids. When an object undergoes acceleration then it is not always necessary that the object is always falling towards the earth. So, option C is incorrect.
