Is velocity always in a straight line?
Constant velocity vs acceleration To have a constant velocity, an object must have a constant speed in a constant direction. Constant direction constrains the object to motion in a straight path thus, a constant velocity means motion in a straight line at a constant speed.
What is difference between linear and rectilinear motion?
Answer: A body/ object is said to be in linear motion when it travels along a straight line or along a curve in a plane. Example- Athlete running along a straight path. Rectilinear motion ( is also a type of linear motion) which can be described by by a moving body/object that travels only straight path.
What is linear motion give two examples?
Some examples of linear motion are a parade of soldiers, a train moving along a straight line, and many more.
What are the two types of linear motion?
The three major types of simple linear motion are constant velocity motion, uniformly accelerated linear motion, and free fall. The basic physics quantities used to describe the motion of an object are: position, distance, displacement, speed, velocity, and acceleration.
What is linear motion class 9?
Linear Motion In linear motion, the particles move from one point to another in either a straight line or a curved path. The linear motion depending on the path of motion is further divided as follows. Rectilinear Motion – The path of the motion is a straight line.
What is the simplest type of motion class 9?
The simplest form of motion is the motion in a straight line. The distance and displacement are the quantities used to determine the final position of the object with respect to the initial position.
What is the simplest motion?
Motion with constant velocity is one of the simplest forms of motion. This type of motion occurs when an an object is moving (or sliding) in the presence of little or negligible friction, similar to that of a hockey puck sliding across the ice.
What is acceleration of class 9th?
Class 9 Physics Motion. Acceleration. Acceleration. Acceleration: It is a measure of the change in the velocity of an object per unit time. Acceleration can be caused either by change in direction of motion or change in speed or both.
What is acceleration written formula Class 9?
Acceleration (a) is the change in velocity (Δv) over the change in time (Δt), represented by the equation a = Δv/Δt. This allows you to measure how fast velocity changes in meters per second squared (m/s^2). Acceleration is also a vector quantity, so it includes both magnitude and direction.
