27-8 Motion in a straight line (Example 2) 物理学是整个自然科学和现代工程技术的基础。英文版大学物理课程的开设,首先是使学生掌握专业所必须的物理基础知识和专业词汇;进而要让学生对物理学的内容和方法、工作语言、概念和物理图像,其历史、现状和前沿等方面,从整
A body of mass ‘m’ is moving with a velocity ‘v’ along a straight line. If the mass and velocity are doubled, then find the ratio of the final kinetic energy to the initial kinetic energy. 1 : 8 4 : 1 8 : 1 More than one of the above None of the above Answer (Detailed...
The second holds that all movement is, of itself, along straight lines. This is Newton's first law, clearly stated in a book published in 1644 — when Newton was still a newborn! Clearly, Isaac Newton studied Descartes. He put that studying to good use as he single-handedly launched ...
there is no important distinction between rest anduniform motionin a straight line; they may be regarded as the same state of motion seen by different observers, one moving at the samevelocityas the particle and the other moving at constant velocity with respect to the particle. Thispostulateis...
and the motion of any ball in sports. Such objects are calledprojectilesand their path is called atrajectory. The motion of falling objects as discussed inMotion Along a Straight Lineis a simple one-dimensional type of projectile motion in which there is no horizontal movement. In this section...

According to motion definition, it is the change of position of an object with respect to time. Understand motion definition, types of motion along with examples, and real-life applications at BYJU'S.
Step 1. Resolve or break the motion into horizontal and vertical components along the x- and y-axes. These axes are perpendicular, so Ax = A cos θ and Ay = A sin θ are used. The magnitude of the components of displacement s along these axes are x and y. The magnitudes of the ...
direction that istangentto its path; for a circular path, for example, its direction at any instant is perpendicular to a line from the point to the centre of thecircle(a radius). The magnitude of the velocity (i.e., thespeed) is the time rate at which the point is moving along ...
Mass. While mass, m, factors into rotational problems, it is usually incorporated into a special quantity called the moment of inertia (or second moment of area) I. You'll learn more about this actor, along with the more fundamental quantity angular momentum L, soon....
