What else can I help you with?
When the electric charge of to objects decreased what happeneds to the force?
Assuming that the only force on the two objects is an electric force. Felectric = k Q q / r2 This is Coulomb's law. K = electrostatic constant, Q and q are the magnitudes of the point charges, and r is the distance between the point charges. As you can see, if you decrease the magnitude of the charge, the electric force decreases. In other words, the objects are less attracted to one another. aside: gravity happens to be modeled the same way.
The largest velocity reached by a falling object is its what?
The largest velocity reached by a falling object is its terminal velocity. Terminal velocity is the constant maximum velocity reached by an object when the drag force is equal in magnitude and opposite in direction to the gravitational force acting on the object.
How do two objects moving at the same speed have different velocities?
Velocity is a vector; to specify velocity, you indicate a speed (a magnitude), and a direction. If two objects move in different directions, their velocities will be different, even if their speeds are the same.Velocity is a vector; to specify velocity, you indicate a speed (a magnitude), and a direction.

What is the relationship between acceleration and the derivative of velocity?
The relationship between acceleration and the derivative of velocity is that acceleration is the rate of change of velocity. In other words, acceleration is the derivative of velocity with respect to time.
How are position, velocity, and acceleration related?
Position, velocity, and acceleration are related in that velocity is the rate of change of position, and acceleration is the rate of change of velocity. In other words, acceleration is the second derivative of position, and velocity is the first derivative of position.

What causes change in velocity?
If an object's velocity changes -- if its speed increases or decreases or if its direction changes -- that means it has accelerated. For an object to accelerate, the sum of the forces acting upon it must be non-zero. So, in other words, forcechanges an object's velocity.
If an objects mass decreases while a constant force acts on it the acceleration is?
The object's acceleration increases. A force enacts a change in momentum, so we have a constant change in momentum. Momentum is mass times velocity, so a force is a change in mass and/or velocity; in this case, the force is simply accelerating the object. So as mass is lowered, its velocity must increase to compensate and keep the force constant. In other words, it accelerates. You can think of pushing a barrel of water up a hill with a leak in it: you're pushing it with a constant force, and as the mass decreases, it's easier to push it up the hill (i.e., you go faster, despite not doing any extra work).
The largest velocity reached by a falling object is its what?
The largest velocity reached by a falling object is its terminal velocity. Terminal velocity is the constant maximum velocity reached by an object when the drag force is equal in magnitude and opposite in direction to the gravitational force acting on the object.
What happens to the force of gravity as mass increases and as the distance between the objects increase?
It decreases. Gravity in inversely proportional to the square of the distance.

Can the words speed and velocity be used interchangeably?
yes. speed is velocity.
How are gravity and distance related?
Gravity is inversely proportional to the square of the distance between two objects, according to Newton's law of universal gravitation. This means that as the distance between objects increases, the gravitational force between them decreases. In other words, the farther apart objects are, the weaker the gravitational attraction between them.
How would decreasing the time it takes you to run a certain didstance affect your speed?
From a basic standpoint: If you take an hour to drive 5 miles, you traveled an average of 5 mph during that trip. Your friend makes the same pilgrimage in half an hour. Your friend therefore traveled 5 miles in .5 hours, which means they average 10 mph. Time and speed are inversely proportional. From a physics standpoint: v = d/t This would mean that velocity and distance are directly proportional and that velocity and time are inversely proportional. In other words, as time increases, velocity decreases; as time decreases, velocity increases.
What are the other words for speed?
Velocity
How are speed and velocity diffrent?
Speed is a scalar, velocity is a vector. In other words, when the direction of the speed is relevant, it is called a velocity.
Science words that start with a v?
Velocity and volume are science words.
