What scientific term describes a change in a gene?
A mutation
When can an object a constant speed but not a constant velocity?
If the velocity is constant there is no acceleration. Speed is not velocity, velocity has speed and direction. I A car going around a circular track at 60 mph keeps the same speed but changes direction and thus accelerates at a constant speed. Velocity is speed in a certain direction. So change the speed but keep direction the same and you change the velocity. or Change the direction while keeping the speed the same and you change the velocity. If the speed is constant, any change of direction is a change in velocity. Driving around in a circle is a case of constantly changing direction.
What is scientific honesty?
It means that you don't change your data to fit the expected results.
What is a change in the frequency of a particular gene in one direction in a population called?
Directional selection.
A change in the direction a plant grows in response to gravity?
A change in plant growth due to gravity is gravitropism. Roots have a tendency to grow in the direction of strongest gravitational pull.
What direction do plate tectonics move in?
They don't move in a specific direction. Every plate moves in it's own direction and sometimes they can change directions.
What scientific name doesnt change?
there are many answers to that question. In fact, most don't change.
Can forces change an objects direction?
If I am reading your question correctly, you want to now if balanced forces can change the direction an object is traveling. The answer is no. Balanced forces always produce no net change, hence the term "balanced". You need an unbalanced force to change the direction of an object, or to set an object in motion from a standstill.
Is acceleration due to change in direction?
Acceleration is defined as the change in velocity, and is a result of a force being applied on the object in question. Acceleration will not always result in an object changing direction, but it is capable of it (in the case of centripetal acceleration, all it does is change the direction.) Acceleration is a vector, therefore a direction must always be given when a value is stated.
How do physicists solve problems?
Physicists, along with other scientists, use the scientific method. This method consists of: Formulation of a question, Hypothesis, Prediction, Testing, and Analysis. Keep in mind that some people change the order sometimes.
Balance force can change an object's direction?
false
Why does it change your question sometimes?
Not everyone has English as a first language, and not every question is written in correct English. In such a case, Supervisors may change the wording to make the question more understandable.
Under what circumstances can an object move in a circular path without being accelerated?
It can't. If there is a change in direction, there is a change in velocity ("velocity" includes the direction), and therefore, an acceleration.It can't. If there is a change in direction, there is a change in velocity ("velocity" includes the direction), and therefore, an acceleration.It can't. If there is a change in direction, there is a change in velocity ("velocity" includes the direction), and therefore, an acceleration.It can't. If there is a change in direction, there is a change in velocity ("velocity" includes the direction), and therefore, an acceleration.
Why does wikianswer change the questions that I ask?
Supervisors correct apparent spelling and grammar errors in questions. Sometimes this causes your question to be merged into an existing but differently worded question asking the same thing, Sometimes supervisors misunderstand a question while "correcting" apparent errors and change the meaning of a question inadvertently.
What causes a spaceshuttle to change in velocity by change in direction?
A change in velocity constitutes a change in direction because velocity includes direction.
What is Rate of change of velocity of an object?
The generic term for change in velocity is acceleration. It may be positive or negative (often called deceleration in non-scientific use) or may be a change in vector (direction of travel). This is because velocity is speed (distance covered per time unit) and direction of travel combined.
What is a force that causes an object to change its motion?
I think this question is not phrased very well. Any force can change objects velocity (speed+direction). If fact that is the definition of the force - F=ma any force, by definition itself, can change objects velocity. Maybe you meant what force can change objects direction of motion? In that case - any force that has a different direction (not the same as direction of motion) Any force can change an object's motion.
