What else can I help you with?
Can be defined as the rate at which velocity changes?
accelerationThe rate at which velocity changes is called "acceleration".
Is acceleration the same as speed?
Acceleration is the rate that speed changes.
What is defined as the rate at which velocity changes?
acceleration
What describes a trains acceleration if it changes speed from 25 m s to 10 m s in 240 s?
negative Acceleration
What is the acceleration of a car that travels in a straight line at a constant speed of 80 km per hour?
if the velocity is constant, the acceleration is zero. The acceleration is the rate at which the velocity changes, so if it stays the same, the car isn't accelerating.
What can acceleration be described as?
Acceleration can be described as the rate at which an object's velocity changes over time. It measures how quickly the object's speed or direction is changing. Therefore, it quantifies how much an object's motion is increasing or decreasing.
How does force affect acceleration when mass is changes?
When force is constant and mass changes, acceleration is inversely proportional to mass. That means that as mass decreases, acceleration increases, and vice versa. This relationship is described by Newton's second law of motion, F = ma, where F is force, m is mass, and a is acceleration.
What it is called when velocity changes?
When velocity changes, it is referred to as acceleration. Acceleration is the rate at which the velocity of an object changes over time.
What is the rate at which an object velocity changes?
Acceleration
How does a change in force effect accelaration?
An increase in force applied to an object will result in an increase in acceleration, given that the mass remains constant. This is described by Newton's second law of motion, which states that acceleration is directly proportional to the force applied to an object. Conversely, a decrease in force will lead to a decrease in acceleration.
What are acceleration and velocity?
'Velocity' means the rate at which position changes, and the direction in which it changes. 'Acceleration' means the rate at which velocity changes, and the direction in which it changes.
Who discovered the acceleration?
The concept of acceleration was first described by Galileo Galilei in the 17th century. He conducted experiments with rolling balls and inclined planes to study how the speed of an object changes over time. He formulated the equation for acceleration as a = Δv/Δt, where a is acceleration, Δv is change in velocity, and Δt is change in time.
What is the rate at which speed or direction changes?
Acceleration
When an object undergoes an acceleration?
when it is acted on by a force
What is the relationship between velocity, time, and displacement when acceleration is constant?
When acceleration is constant, the relationship between velocity, time, and displacement can be described by the equations of motion. The velocity of an object changes linearly with time when acceleration is constant. The displacement of the object is directly proportional to the square of the time elapsed.
Can be defined as the rate at which velocity changes?
accelerationThe rate at which velocity changes is called "acceleration".
What are the quantities of motion?
The quantities of motion are described by the concepts of speed, velocity, acceleration, and momentum. Speed is the rate of motion, velocity includes speed and direction, acceleration is the rate at which velocity changes, and momentum is the product of an object's mass and its velocity.
