What two ways can speed be described?
Instantaneous speed is the magnitude of the instantaneous velocity. Instantaneous speed is a scalar quantity, as it has no direction specified. Average speed is the total distance traveled divided by the elapsed time. (Average speed is not the magnitude of the average velocity.)
What term is used to describe the rate of change in speed?
Acceleration is defined as the rate of change of velocity. Velocity is a vector, which means it contains a magnitude (a numerical value) and a direction. So the velocity can be changed either by changing the speed or by changing the direction of motion (or both).
Which of the following may increase or decrease the speed of an object?
Acceleration is the force applied to an object changing its speed, direction, or both. Acceleration may increase or decrease the speed or velocity of an object.
What is the rate of decrease in velocity?
The rate of change of velocity is called acceleration and the kind of motion is known as accelerated motion.
How do you explain speed in science?
Speed is the time rate at which an object is moving along a path, while velocity is the rate and direction of an object’s movement. Put another way, speed is a scalar value, while velocity is a vector.
How do you explain speed?
Speed is a scalar quantity that refers to “how fast an object is moving.” Speed can be thought of as the rate at which an object covers distance. A fast-moving object has a high speed and covers a relatively large distance in a short amount of time.
Which of the following may increase or decrease the speed of an object?( A acceleration B velocity C motion D frame of reference?
The velocity is the speed and direction of a moving object. Acceleration is the force applied to an object changing its speed, direction, or both. Acceleration may increase or decrease the speed or velocity of an object. Deceleration is also a force applied to an object changing its speed, direction, or both.
Under what conditions when force is applied on an object will decrease and increase its velocity?
When a force is applied on an object, it may change its is in the direction of motion, the speed of the object increases. If direction opposite to the motion, then it results in a decrease in speed.
How does velocity decrease?
If the line slopes downward, like the line between 7 and 10 seconds, velocity is decreasing and acceleration is negative. Negative acceleration is called deceleration.
What does it mean to speed up?
To increase in speed To move or proceed further along a course
How do catalysts increase or decrease the speed of a reaction?
The catalysts can be used to increase or decrease the speed of a chemical reaction. The catalysts which reduce the speed of a reaction are called negative catalysts. They decrease the speed of the reaction by increasing the activation energy of the reaction. What cuases speed to increase and decrease?
What is it called when gears are rotating at the same speed?
The component used to ensure that the main shaft and the main shaft gear about to be locked to it are rotating at the same speed is known as a: synchronizer When discussing the rotation of gears and shafts in a truck transmission, which of the following terms can be used to describe clockwise rotation?
What is the meaning of gradually increasing?
gradually increasing. and counting phrase. used for saying that a number is continuing to increase as time passes. by a factor of something a radical increase or decrease is extremely large and important. reducible adjective. able to be reduced. rising adjective. increasing in size, amount, quality, or strength. runaway
