Is it possible for a body to have an acceleration when moving with constant speed explain?
Yes, it's acceleration will be zero because the velocity isn't changing, but it has an acceleration. Think of it in terms of integration and derivation. Acceleration is the derivative of velocity, so if velocity is a constant number the acceleration must be zero.Generally if value of acceleration is "zero", we consider it to mean that there is NO acceleration. The question that was actually answered above was "Can acceleration be DEFINED fora body moving at constant speed?"It is possible for an object to be moving at a constant angular speed and yet have an effective acceleration in a tangential direction.===========================================Both of you guys are missing the most important point here, with the resultthat you have to twist your own arm almost to the point of dislocation in orderto state an answer.The essential underlying consideration is that, contrary to popular misconception,"acceleration" does not mean 'speeding up', or even 'changing speed'. It means"change in velocity", and "velocity" means "speed anddirection". If either speedor direction change, then that means there is 'acceleration'.The answer to the question is simple, and almost entirely non-technical. It is:"Yes, because 'acceleration' means change of either speed or direction. So, ifthe direction of the body's motion is changing, then the body has acceleration,even if its speed is constant."
Explain what is on the y-axis and x-axis in order to get acceleration?
In case of uniform acceleration,the graph will be a straight line with a +ve slope ,if we are taking velocity along Y-axis and time along X-axis.hence it's slope will give u acceleration.
What is newtons 2nd law of motion in simple terms?
It isn't really simple to explain; to get a thorough understanding, you MUST understand a few basic concepts. See below. But basically, a force will result in an acceleration; the amount of acceleration an object experiences will depend on the force (more force will result in more acceleration), and on the object's mass (more mass will result in less acceleration). The basic concepts that are important to understand are the following: * Acceleration as a rate of change in velocity - how fast velocity changes. * Both velocity and acceleration are vectors. * A reduction in speed is a change in velocity; so is a change in direction, even if the speed doesn't change. In this case, in physics you would still talk about "acceleration"; even though in popular terms, "acceleration" is usually understood as an increase in speed. * The NET FORCE must be considered - the vector sum of all forces that act on an object. It is quite common that a force acts on an object, but it doesn't accelerate - in which case there is a counter-force that is balancing the first force.
Explain how distance time and velocity are related to each other?
They are related through the formula distance = time x velocity (assuming constant velocity).
You are in a car going 70 km h and another car passes you going in the opposite direction at 70 km h Do both cars have the same velocity Explain?
You already answered the question. Both cars are traveling at 70kmph, which is the same velocity.
Explain the circumstances when the acceleration and the velocity of car are parallel?
when velocity of a car is increasing then velocity and acceleration are parallel to each other.
When is velocity parallel to acceleration?
Velocity is parallel to acceleration when an object is moving with constant speed in a straight line, as the direction of the velocity and acceleration vectors are aligned. This means that the object's speed may be constant, but its direction can change.
Can a moving body have velocity and acceleration in opposite directions explain with in example?
Of course. A car with brakes applied and slowing down has forward velocity and rearward acceleration.
Explain the circumstances in which the velocity and acceleration of the body is parallel?
The velocity and acceleration of a body are parallel when the body is moving along a straight path with a constant speed. In this case, the velocity is constant, and since acceleration is the rate of change of velocity, it is zero. Therefore, both the velocity and acceleration vectors are parallel and pointing in the same direction.
Can you have a zero acceleration but non zero velocity explain it with help of a graph?
Yes, it is possible to have zero acceleration with a non-zero velocity. This occurs when the velocity is constant. On a velocity-time graph, a flat, horizontal line represents constant velocity, while a zero slope (flat line) represents zero acceleration.
Explain Why a change in velocity effects acceleration?
Acceleration is the rate of change of velocity over time. Therefore, when there is a change in velocity, it directly affects acceleration because acceleration is influenced by how quickly or slowly an object's velocity changes. If an object speeds up, slows down, or changes direction, its velocity changes, leading to a corresponding change in acceleration.
How is newton related to acceleration and velocity?
Newton's second law of motion mathematically relates acceleration to force as F = ma, where F is the force applied to an object, m is its mass, and a is its acceleration. Acceleration is also related to velocity through the equation a = Δv/t, where Δv is the change in velocity over time t. So, Newton's laws help explain the relationship between acceleration, velocity, and force.
Explain why the slowing down of a moving object is considered to be a form of acceleration?
Acceleration is the change of velocity, with direction. Therefore slowing down is a change in veolcity, so is considered to be acceleration (just negative acceleration).
Can changing of velocity results in acceleration. Explain.?
Acceleration is change in velocity over time. a = vf - vi/Δt, where a is acceleration, vf is final velocity, vi is initial velocity, and Δt is the time interval. For example, a car accelerates from rest to 15m/s in 5.9s. What its acceleration? vi = 0m/s, vf = 27m/s, Δt = 5.9s, a = ? a = 27m/s - 0m/s/5.9s = 4.6m/s/s = 4.6m/s2
Do you agree with the statement an object with a zero velocity can have an acceleration greater than zero?
Yes, an object with zero velocity can have an acceleration that is greater than zero if there is a change in its velocity over time. Acceleration is the rate of change of velocity, so even if the object starts with zero velocity, it can still accelerate if its velocity increases or decreases.
Explain the difference between acceleration and deceleration?
Acceleration refers to an increase in speed or velocity, while deceleration refers to a decrease in speed or velocity. Acceleration can be positive (speeding up) or negative (slowing down), while deceleration is always negative. Both terms refer to changes in an object's velocity over time.
Which term explain whether an objects velocity has increased or decreased over time?
You're fishing for "acceleration", but your description doesn't support that answer.Acceleration is also present if the direction of motion has changed, even if the speed(the size of velocity) hasn't changed.Acceleration explains the change in an objects velocity over time.
