In case of a projectile motion, what is the angle between the velocity and acceleration at the highest point? The kinetic energy of a projectile at the highest point is-. Acceleration of a particle under projectile motion at the highest point of its trajectory is :. At the uppermost point of a projectile, its velocity and acceleration are at an angle of. Reason : At the highest point, velocity of projectile will be in horizontal direction only.

Chapter 6 Uniform Circular Motion and Gravitation discussed only uniform circular motion, which is motion in a circle at constant speed and, hence, constant angular velocity. According to the sign convention, the counter clockwise direction is considered as positive direction and clockwise direction as negative. The faster the change occurs, the greater the angular acceleration. In equation form, angular acceleration is expressed as follows:. Suppose a teenager puts her bicycle on its back and starts the rear wheel spinning from rest to a final angular velocity of rpm in 5.

If theta is the angle between the velocity and acceleration

In Kinematics , we studied motion along a straight line and introduced such concepts as displacement, velocity, and acceleration. Two-Dimensional Kinematics dealt with motion in two dimensions. Projectile motion is a special case of two-dimensional kinematics in which the object is projected into the air, while being subject to the gravitational force, and lands a distance away. In this chapter, we consider situations where the object does not land but moves in a curve. We begin the study of uniform circular motion by defining two angular quantities needed to describe rotational motion. When objects rotate about some axis—for example, when the CD compact disc in Figure rotates about its center—each point in the object follows a circular arc. Consider a line from the center of the CD to its edge. Each pit used to record sound along this line moves through the same angle in the same amount of time. The rotation angle is the amount of rotation and is analogous to linear distance.
