Average acceleration =
(change in speed over some period of time) divided by (time for the change)
Newton's first equation of motion states that an object will remain at rest or in uniform motion in a straight line unless acted upon by an external force. In other words, an object will maintain its velocity unless a net external force is applied to change it.
The motion along a straight line is known as rectilinear motion.
The trajectory of the motion is a straight line.
The average velocity of an object is equal to its instantaneous velocity in uniform motion. Uniform motion occurs when an object moves at a constant speed in a straight line, resulting in a constant velocity throughout the motion.
If an object moving along a straight line,path,track etc.It,s motion is said to be straight line motion
I believe linear motion is simply straight motion because linear means straight
means motion of equation
linear motion.
For an object moving with uniform motion, the equation of motion does not change. The equation remains the same as it describes the relationship between an object's position, velocity, and time regardless of whether the motion is uniform or non-uniform. Uniform motion implies constant velocity, so the acceleration term in the equation of motion is zero.
The answer depends on how the body is moving:in 2-dimensional space or 3-d,in a straight line or notat a constant velocity of notat a constant acceleration or not.For example, the equation for a body moving in simple harmonic motion isd2y/dx2 = -w2*x
Velocity is a vector quantity that describes the rate at which an object changes position. It includes both the speed of the object and its direction of motion. Linear motion, on the other hand, simply refers to the movement of an object along a straight path without considering its speed or direction.
Acceleration involving only a change in direction is known as centripetal acceleration. It occurs when an object moves in a circular path at a constant speed, and the centripetal force acts towards the center of the circle to keep the object from moving in a straight line.
