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.

How could two observers measure a different speed for the same moving objects?

They would have to have different base velocities. One on the ground, the other in a moving vehicle.


Is there more force created when 2 objects meet in motion or when 1 object is still?

Assuming all of the objects have the same mass, the answer depends on their combined velocities. If the combined vector component of velocity of two objects is the same as the velocity of the single moving object, then the force of impact will be the same. So if the two are moving in opposite directions along the same path, they will generate the same amount of force as a single object moving at a velocity that is equal to the combined velocities of the two. If the velocities are different, the force varies accordingly.


Can a body posses two velocities at a specific time?

For different observers (moving at different velocities), the object will have different velocities (relative to the corresponding observer). For one and the same observer, the body will have only one velocity at any given time.


How do two objects moving at the same speed have different velocities?

A lot of people think that 'velocity' is just a fancy word for 'speed', that you usewhen you want to sound smart. But it isn't. The two words mean different things.'Speed' just means how fast you cover distance. 'Velocity' means how fast you coverdistance and what direction you do it in. If you're driving around a circular track at30 miles per hour, your speed isn't changing; but your velocity is, because yourdirection keeps changing.Two objects moving at the same speed but in different directions have different velocities.Because their directions are different.


Two objects with the same velocity must be moving in the same what?

They would be traveling at the same speed. Two objects moving with the same velocity must be moving in the same direction and at the same speed. The reason for this is because velocity is speed in a specified direction. Another way to say that is to say that velocity is speed with a direction vector. It is a physical quantity with magnitude and direction. Two objects moving with the same speed could be moving toward a head-on collision. Or they could be moving along convergent, divergent or skewed paths. Not so with two objects that have identical velocities. They are moving on the same or on parallel courses, and they are moving at the same speed.


What are Four different collision scenarios of conservation of momentum?

Elastic collision: objects bound against each other after the collision. - One is moving and the other is at rest. - Both objects are moving. Inelastic collision: objects stick together after the collision. - One is moving and the other is at rest. - Both objects are moving.


How are a body at rest and body moving similar in velocity?

A body at rest and a body in motion have completely different velocities.Magnitude of velocity:At rest . . . zeroMoving . . . not zeroDirection of velocity:At rest . . . no directionMoving . . . some direction


If two objects have the same momentum do their velocities necessarily have the same directions?

=== === Since momentum is a vector and not a scalar quantity, to have the same momentum, they must have the same direction. Remember, vectors have magnitude and direction. Speed is the magnitude part of velocity. Since momentum is the product of mass (a scalar) and velocity (a vector) if two objects are moving in different directions, even if they have the same mass and speed, their momentums are different.

Does moving objects have impulse?

yes moving objects have impulse


How do you be safe with moving objects?

keep distance with moving objects.


What are differences in colors of moving objects in space that are approaching and moving objects that are moving away?

Objects moving toward you will have a blue shift in their spectrum and objects moving away from you will have a red shift in their spectrum. This is known as a doppler shift.


Does the law of inertia apply to moving or non moving objects?

It applies to both moving and non-moving objects.


How different positive velocity and negative velocity?

Positive and negative velocities are simply velocities in opposite directions.Before you start working on the situation, you definewhich direction you'regoing to call positive. Anything you find moving the other way has negativevelocity.


How can two objects of different mass have the same momentum?

Momentum and is the product of mass and speed. So a fast-moving objects can have the same momentum as a slower-moving object with grater mass.



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.


What are electromagnetic waves with high energy called?

Gamma rays. Only extremely hot objects or particles moving at very high velocities can create high-energy radiation like X-rays and gamma-rays.


How do grasshoppers detect moving objects?

Grasshoppers detect moving objects using their compound eyes. These eyes cause a flicker effects as objects move past them, allowing grasshoppers to see moving objects better than objects that are still.

Why do moving objects get warmer than non-moving objects?

Objects moving against the force of friction dissipate energy in form of heat. Some part of this heat, is absorbed by the body itself and objects get warm.
