What Are The Four Types Of Speed-time Graphs? Time graph for constant speed. Speed-Time graph with constant acceleration. Speed-time graph with increasing acceleration. What are speed-time graphs? Speed-time graphs are very useful when describing the movement of an object. We can use them to determine whether or not the object is moving at any point
Is U Final Or Initial Velocity? uInitial velocity v Final Velocity t time taken s displacement a acceleration What does U mean in velocity? u is initial velocity in m/s. t is time in s. For example, a car accelerates in 5 s from 25 m/s to 3 5m/s. Its velocity changes by 35 –
What Adds More Kinetic Energy? If you double the mass of an object, you double the kinetic energy. If you double the speed of an object, the kinetic energy increases by four times. What affects kinetic energy the most? The two main factors that affect kinetic energy are mass and speed. Why? Because the motion
Is VX And VY Constant? Here are some formulas that describe projectile motion: Thus the vertical velocity (Vy) is continually increasing. The horizontal velocity (Vx) remains constant and is equal to Vxo. Why does VX remain constant? In case of projectile motion the vertical component of particle’s velocity changes continuously because of the force acting
Is Velocity Always In A Straight Line? Motion with Constant Velocity: When an object is moving with constant velocity, it does not change direction nor speed and therefore is represented as a straight line when graphed as distance over time. Is velocity the same as speed in a straight line? In everyday usage, the terms
What Are 5 Differences Between Speed And Velocity? Speed Velocity Speed ascertains how fast a body moves. Velocity ascertains the object’s speed and the direction it takes while moving. What are the four difference between speed and velocity? It is the rate at which a particular distance is covered by an object. Velocity refers to
Is Work Done At A Constant Speed? When an object is moving with constant velocity, it means that there is 0 acceleration and hence no force and no work done. Is work done dependent on speed? No work done not depend upon the velocity of the body . its depend on the force applied and
What Are The 3 Causes Of Acceleration? Any change in velocity is acceleration. The amount by which an object accelerates depends on three things. They are the size of the force, the direction in which the force acts, and the mass of the object. If two forces act on the same object, the greater force
What Are Vectors Used For? Vectors are used in science to describe anything that has both a direction and a magnitude. They are usually drawn as pointed arrows, the length of which represents the vector’s magnitude. Why are vectors useful? Why are vectors useful? ▫ Vectors can be used to describe any sort of physical
What Are Three Examples Of Velocity? So whether its a car moving, a ball being dropped, or the earth moving around the sun, all of these things have a velocity! What are five examples of velocity? Examples: 1) Revolution of Earth around the sun. 2) Revolution of moon around the earth. 3) Velocity of a
