Do both cars have the same velocity if they are going in different directions at seventy miles per hour?

No, they don't. Velocity is a vector - made up of both a magnitude (number), and a direction. If any of the two changes, the velocity is not the same.
If you are interested only in the magnitude, you talk about "speed", not "velocity".

What is a real life example of an opposite ray?
Darth Maul's double light saber because the rays from the light saber are going 2 different directions.
Do speed and velocity have same meaning?
No. It's confusing unless you're into physics or mathematics but velocity is a vector quantity with speed is one aspect. Velocity includes speed and the direction of motion. A car is going 60 miles per hour as speed. A car is going 60 MPH due north is velocity.
Is it possible for velocity to have a negative value?
Yes velocity is a vector that has both speed and direction. So if you are going 30 mph in one direction that may be positive, but if you are going in reverse that may be negative.
How is the initial velocity zero but the acceleration is not?
Going back to definitions, Velocity is change of distance with time; and acceleration is change in velocity with time. Initially, the velocity is zero, as is the acceleration, BUT the Force of Gravity attracts the falling mass, and causes velocity to appear. But the continued application of the Force of Gravity causes the velocity to increase. And as we know, increase in velocity is acceleration. [space for QED]
You are in a car going 70 kmh and another car passes you going in the opposite direction at 70 kmh. do both cars have the same velocity?
No. Velocity is a vector, so it has both a magnitude and a direction. If the velocity of your car was heading in the positive direction, then the other car is moving in the negative direction. The velocities are NOT the same!
How the velocity of an escalator that is going up different from the velocity of one that is going down at the same speed?
Speed is a scalar, velocity is a vector. Two objects moving at the same speed but in opposite directions will have opposite velocities. If the velocity of the elevator going up is v, the velocity of the elevator going down will be -v.
When you combine 2 velocities going in opposite directions how is the resultant velocity found?
To find the resultant velocity when combining two velocities going in opposite directions, you simply subtract the smaller velocity from the larger velocity. The direction of the resultant velocity will be in the direction of the larger velocity.
When you combine two velocities going in opposite directions how is the resultant velocity found?
The resultant velocity is found by subtracting the smaller velocity from the larger one if they are in opposite directions. This is because the velocities are working against each other to some degree, resulting in a net velocity that is the difference between the two.
What are things that come in groups of seventy?
Quorum of the seventy Seventy friends going to the mall Seventy hummingbirds A pile of seventy coins
What does a diagram of two objects with the same speed but a different velocities look like?
A diagram of two objects with the same speed but different velocities would show two arrows of equal length representing their speed, but pointed in different directions to indicate their different velocities. The arrows would be parallel to each other, indicating that the objects are moving at the same speed.
Why does a compass point in different directions?
Its ovious why a compass points in different directions. For example, if your going north, the compass points north because your going that direction. Theres also a magnet concealed in the compass. How does the compass know what direction yoiur going. Earth it self is a magnet. When you head that direction, it will point
If an object has two velocities are going in opposite directions would the overall velocity of the object be positive or negative?
It's positive in the direction of the greater one, and negative in the direction of the smaller one.
What happens when light gets scattered?
It stops going only one way and starts going every which way.
What is speed and how is speed different from velocity?
Velocity is speed plus direction. If you say you are traveling at 54 miles per hour, you are giving your speed. If you say you are going north at 54 miles per hour, you are giving your velocity.
What is the difference between constant velocity and average velocity?
Constant velocity means the object is moving at a consistent speed in a straight line with no change in direction. Average velocity, on the other hand, takes into account changes in velocity over a given time interval and is calculated as the total displacement divided by the total time elapsed.
What is the separation of the two bodies with initial velocity 10 ms after 2s?
That's going to depend on the directions of each of the two initial velocities. It's also going to depend on who measured the initial velocities, where he was standing, how he was moving, and with respect to what else, etc.
How are hot air balloons steered?
Hot air balloons are steered by changing altitude. The air currents are often going different directions at different altitudes, and by changing altitude you can get into an air current going the direction that you want to go. This isn't complete control like the steering on a car or airplane, you are still limited to the directions that the wind is going, but you have some control.
