Does gravity stop a ball from rolling?
Momentum is the product of mass and velocity. When an object slows down, the object reduces in velocity. Since Mass is constant, when velocity reduces momentum reduces. thus momentum can be what stops a rolling object. However, a resistive force the reason for the reduction of velocity and subsequently halting.
Does a boulder rolling down a hill have momentum?
Yes, a boulder rolling down a hill has mass and velocity. Therefore, it has momentum because p = mv (momentum = mass x velocity).
When acceleration and velocity vectors are pointing in opposite directions the object is?
This would indicate negative acceleration, which would mean that the object in question is speeding up.
What is the definition of vertical velocity?
Vertical means up and down; so the vertical velocity is an indication of how quickly an object is rising or falling. If the object is moving at an angle (such as an airplane taking off or landing) then it would be more accurate to call it the vertical component of the object's velocity.
Zero velocity what is it?
This means an object is at rest, at least relative to a certain frame of reference. For example, the object may be laying, not rolling, on the ground, and will remain at zero velocity until another force acts on it, or may be an object that was thrown straight up and is being slowed down and pulled back down by gravity, which will reach a velocity of 0 instantaneously and then begin to fall back down. This always happens at the object's maximum height.

Does rolling friction push the same direction as the velocity of an object?
If it did, then any rolling object would speed up because of friction. Since everythingthat rolls actually slows down, the virtual 'force' of friction must be exactly oppositethe direction of an object's motion.

What is a negative slope on a velocity-time graph indicates the object is down?
A negative slope on a velocity-time graph indicates a decreasing velocity over time, which means the object is slowing down. As time increases, the velocity decreases.
Why is velocity needed to measure momentum?
In physics, the momentum of an object is the amount of energy it has moving in a direction. It is a product of its mass (weight) and its velocity (speed and direction) as in (momentum = Mass times velocity). Momentum changes when speed is increased or decreased, its direction changes, or its mass changes. An example of changing momentum is an object in space such as a meteor falling to the earth. Gravity can make it come down faster increasing its momentum. Atmospheric friction heats up the object causing some of it to burn away reducing its mass and decreasing its momentum. Another example of momentum is a snowball rolling down a snow covered mountain. Gravity pulling it down increases it speed (velocity) and momentum. Rolling down in snow, it accumulates snow, gets larger, increasing in weight (mass) and momentum.
What is the definition for rolling friction?
Wheels, ball bearings, the Egyptians building the pyramids using tree trunks to move the stones. An example of rolling friction would be like a skateboard rolling on a sidewalk. car running up a hill. someone pushing a wheel barol A bowling ball
State the ways velocity can change?
the velocity of an object changes when it speeds up or slows down.
What is the difference between static and rolling friction?
static is standing still, and rolling is movement. static is the friction that prevents the object from moving, rolling is the friction that slows down the object while it is motion.
How can you use integers to represent the velocity and the speed of an object?
This was the essential question on a homework assignment. Speed tells how fast an object is moving but it does not tell the direction. Velocity tells how fast an object is moving and it also tells the direction. When velocity is positive, the object is moving up. When velocity is negative, the object is moving down.
