What needs to be applied in order to change an objects velocity?
To change an object's velocity, you need to apply a force to it. The force will cause the object to accelerate, thus changing its velocity. The magnitude and direction of the force will determine the extent and direction of the velocity change.
In order to change the velocity there needs to be a?
To need force
Which quantities do you need to know in order to determine the change in an objects momentum?
To determine the change in an object's momentum, you need to know the initial momentum of the object (mass x initial velocity) and the final momentum of the object (mass x final velocity). The change in momentum is equal to the final momentum minus the initial momentum.
What must applied in order to change an object's velocity?
force
What must be applied in order to change object velocity?
force
What must be applied in order change an object's velocity?
force
Do two skaters traveling in different directions at the same speed have the same velocity?
No. Velocity is the combination of a speed and its direction. In order fortwo objects to have the same velocity, they must be moving at the samespeed, and in the same direction.
Does everything need energy to move?
Newton's laws of motion apply here: things only change velocity when a force is acting upon them. While objects that are moving have (potential) kinetic energy, no extra energy is required to keep them moving: energy would be required to change their motion.
What information do you need in order to find a object's acceleration?
To find an object's acceleration, you need its initial velocity, final velocity, and the time it takes to change from the initial velocity to the final velocity. The formula for acceleration is (final velocity - initial velocity) / time elapsed.
Is it true or false that a body traveling at constant speed changes its direction without a change in its velocity?
False. A body traveling at constant speed does not change its velocity, which includes both speed and direction. Therefore, in order to change direction, the body would need to change its velocity, which also involves changing its speed.
Anya knows the velocity of an object. What else does she need to know in order to find the objects momentum?
The mass of the object.
How do you get velocity using mass and displacement?
You cannot directly obtain velocity using only mass and displacement. Velocity is calculated by dividing the change in displacement by the change in time. In order to determine velocity, you would need to know the time it takes for an object to travel a certain distance.
