What does the speed of an object tell you about that objects motion?
The speed of an object tells you how fast it is moving. It does not provide information about the direction of the object's motion or whether it is changing direction. To fully describe an object's motion, you would need to also consider its velocity, which includes both speed and direction.
What is needed to change the speed of an object?
To change the speed of an object, you need to apply a force to it. The magnitude of the force and the direction in which it is applied will determine how the speed changes. If the force is in the same direction as the motion, the object will accelerate; if the force opposes the motion, the object will decelerate.
How can one determine the velocity vector of an object?
To determine the velocity vector of an object, you need to know both the speed and direction of the object's motion. The velocity vector is a quantity that includes both the magnitude (speed) and the direction of the object's motion. It is typically represented as an arrow pointing in the direction of motion, with the length of the arrow representing the speed. You can calculate the velocity vector by measuring the object's speed and the angle of its motion relative to a reference point.
What three things do you need to now to describe the velocity of an object?
To describe the velocity of an object, you need to know its speed (magnitude of velocity), direction of motion, and reference point for measuring the motion.
How do you find velocity given only mass and speed?
You can't, because you don't have enough information. In order to find velocity, you need to be able to find the speed and the direction of motion. You have the speed, but you have no information that you can use to determine the direction in which the object is moving. Mass doesn't help.
Two physical quantities used to describe the motion of an object?
Some of the more basic measurements of an object we can take are time and position (or distance). From these values we can calculate things (like speed and direction) that we use to describe its motion.
Is it t the motion of an object can be measured by looking at it?
No, the motion of an object cannot be accurately measured simply by looking at it. To measure an object's motion, you need to track its position over time using tools like rulers, stopwatches, or motion sensors. By analyzing the data collected, you can determine the object's speed, velocity, and acceleration.
What is needed to determine whether an object is in motion?
To determine if an object is in motion, you need to compare its position at different points in time. If the object's position changes over time, it is in motion. Additionally, measuring its speed or velocity can provide further confirmation of its motion.
What two things do you need to know to describe the velocity o an object?
To describe the velocity of an object, you need to know its speed (magnitude of the velocity) and its direction of motion. Velocity is a vector quantity that combines both speed and direction.
How two things do you need to know to describe the velocity of an object?
To describe the velocity of an object, you need to know both the speed (magnitude of the velocity) and the direction of the object's motion. Velocity is a vector quantity that includes both of these aspects.
Why do you need a frame of reference to determine speed of an object?
A frame of reference is needed to determine the speed of an object because speed is a relative measure that depends on the observer's perspective. By having a reference point that is stationary or moving at a known speed, we can compare the object's motion to that reference point and calculate its speed accurately.
How can you find the speed and velocity of an object?
Speed equals the total of distance traveled divided by the total time of travel example: A bicycle total distance is 5km. The total of time is 1/4 of a hour 0.25 a hour. speed=5km/0.25h=20km per hour
