How is motion describe when the velocity of an object changes by the same amount each second?
That is called constant acceleration.
When velocity changes by the same amount over each time period acceleration is?
Acceleration is constant.
The amount of kinetic energy an object has depends upon what factors?
Kinetic energy equals 1/2 mass times the velocity squared, so mass and velocity (speed)
What happens to the momentum of two objects which collide and stick together?
In a collision, a force acts upon an object for a given amount of time to change the object's velocity. The product of force and time is known as impulse. The product of mass and velocity change is known as momentum change. In a collision the impulse encountered by an object is equal to the momentum change it experiences.Impulse = Momentum Change. What happens to the momentum when two objects collide? Nothing! unless you have friction around. Momentum#1 + Momentum#2 before collision = sum of momentums after collision (that's a vector sum).
How much more power is required to double an objects velocity in air?
power is a rate of energy transfer. given enough time, any positive amount of power could do this.
How is motion describe when the velocity of an object changes by the same amount each second?
That is called constant acceleration.
Is the change of an objects velocity divided by the amount of time required for change to occur?
That is called acceleration.
The rate at which an object changes position is called what?
A change in position in a certain amount of time is called motion.
Why is momentum caused?
momentum is caused by inertia. all objects have inertia, which means if they are moving at a certain velocity or are at rest they will continue to move at that velocity or remain at rest unless acted on by a force. Objects of more mass have greater inertia, so the amount of momentum is equal to the product of an objects mass and the magnitude of its velocity.
When velocity changes by the same amount over each time period acceleration is?
Acceleration is constant.
What do you need know to find an objects velocity?
The distance it travels in a caertain amount of time as well as the direction
The amount of kinetic energy an object has depends upon what factors?
Kinetic energy equals 1/2 mass times the velocity squared, so mass and velocity (speed)
Acceleration is what?
ACCELERATION- A measure of the rate at which a defined amount of matter increases/decreases its velocity, measured in change in velocity over a period of time.=========================Answer #2:Acceleration is any change in the speed or direction of motion.
What is the demand curve for money?
M=(P*Y/V) Demand for money= (Price level * Output)/Velocity of money, where velocity equals amount of times money changes hands in a period.
Why you calculate momentum?
momentum is caused by inertia. all objects have inertia, which means if they are moving at a certain velocity or are at rest they will continue to move at that velocity or remain at rest unless acted on by a force. Objects of more mass have greater inertia, so the amount of momentum is equal to the product of an objects mass and the magnitude of its velocity.
What does mass mean in physic properties?
Mass is a property that gives objects the following:* It provides objects with weight. (Note: weight = mass x gravity) * It provides objects with inertia. The higher the mass of an object, the harder it is to change its velocity.
What law does this describe law states that for a fixed amount of gas at a constant pressure the volume of a gas changes and the temperature of the gas changes too?
Charles law
