What two things must you know to determine speed?
Speed is the rate at which an object moves. To determine the rate at which that object moves, we'll have to look at a given distance that it covered when it moved, and at the time it took to cover that distance. The distance per unit of time is the speed of the object.
If you know the distance of an object has traveled in a certain amount of time you can determine the?
speed
If you know the distance an object has travled in a certian amount of time you can determine?
Speed.
If an object is moving at a constant speed in one direction what is needed to change its speed or direction?
An unbalanced force
What is the rate at which an object is moving at a given instant called?
speed if no direction is needed velocity if direction is needed
Why is it not possible to use sonar to determine the speed of an object travelling faster than the speed of sound?
Sonar is sound waves bounced off a object so if you are going the speed of sound the waves cannot bounce off the object and determine the speed of the object
Determine if the momentum of an object moving in a circular path at constant speed is constant.?
determine if the momentum of an object moving in a circular path at constant speed is constant.
How are average speed and instantaneous speed alike?
Average speed and instantaneous speed are both measurements of the speed of an object. The instantaneous speed measures how fast the object is going at a particular moment, while average speed shows how fast the object was moving in total over time.
Is speed and distance the same thing?
No, distance and speed are two separate measurements. Distance is how far an object moves relative to speed and time, and speed is how fast an object moves relative to time and distance.
What measurements are needed to determine the entire mass of the Milky Way Galaxy?
The average stellar mass x the number of stars ______________________________ We can calculate the mass of the Milky Way by observing the speed at which stars orbit the center, as long as we can determine how far away they are from the center.
What two factors must be known to determine the velocity of an object in motion?
The object's speed and direction.
How do you determine the speed of a moving object?
The average speed of an moving object is determined by using the formula velocity=distance/time or v=d/t.
Is the momentum of an object moving in a circular path at a constant speed is constant?
determine if the momentum of an object moving in a circular path at constant speed is constant.
What two things must you know to determine speed?
Speed is the rate at which an object moves. To determine the rate at which that object moves, we'll have to look at a given distance that it covered when it moved, and at the time it took to cover that distance. The distance per unit of time is the speed of the object.
What is the equasion used to determine the momentum of an object?
Momentum = (mass) multiplied by (speed)
What two factores determine how much kinetic kinetic an object has?
Its the mass and the speed
If you know the distance an object has travled in a certian amount of time you can determine?
Speed.
