I don't see how anything can "act against momentum"; momentum is always conserved. If there is friction, the movement of the object will be slowed down; but in this case, momentum is transferred to the air, or whatever is slowing down the object in question. Total momentum will be conserved.

Will a heavy bobsled go down a track faster than a light one?
A little. Momentum is mass times velocity. The more momentum and object has the harder it is to stop. So the more momentum a bobsled has the more effective it will be against the forces trying to slow it down such as friction, wind resistance, drag, etc. However, this does assume that the bobsled team can get the heavier sled up to the same speed as a lighter one.
What types forces does act on water tank?
These forces may be either external or internal. As Surface forces act on the surface of the water body by direct contact.
What kinds of forces can act on an object?
Normal force can act on an object
In newtons third law the action and reaction forces?
The two forces are of the same magnitude, act in opposite directions, and act on different objects.
Which are the interolecular forces that can act between non-polar molecules?
London dispersion forces
The total amount of momentum of a group of objects does not change unless outside forces act on the objects?
Momentum
What forces act during car crash test?
Momentum, kinetic energy
What are some forces that act on a ball when you throw it in the air?
Kinetic energy, momentum, gravity.
The total momentum of a group of objects is conserved unless?
b. outside forces act on the objects.
How does friction affect interia?
Friction does not affect inertia, but it affects momentum. Momentum is the product of the mass of an object and its speed. Friction forces, if present, will always act to decrease the momentum of a moving object.
What are the forces that resist outside forces?
They are inertia and momentum. If an object is in motion it tends to "try" to stay in motion, and an object at rest does the same to stay put. The forces still act on it, although the forces are slightly weaker.
The momentum of an object depends on what two forces?
The amount of momentum that an object has is dependent upon two variables: how much stuff is moving and how fast the stuff is moving. Momentum depends upon the variables mass and velocity. In terms of an equation, the momentum of an object is equal to the mass of the object times the velocity of the object.
Forces that maintain motion?
momentum
Can balance force bring a body to rest?
Balanced forces cannot bring a body to rest. Balanced forces can act on a body which is already at rest or in motion but equal forces cannot change a bodies acceleration, kinetic energy or momentum.
What is the law of concervation for momentum?
The law of conservation of momentum (for example linear momentum), says that if no external forces act on a body or if the sum of all external forces on the body is zero, then its momentum remains constant. This means that if I don't push an object that in its initial state stands still, than this object will remain still. And then again: if I don't exert a force (push or pull etc.) upon an object that moves with a constant speed, then its speed will remain constant.
When no outside forces act on asystem of objects what do the objects do?
If there are no outside forces acting on a system of particles the total momentum of the system will remain constant; i.e. the center of mass of the system will remain at rest or move at constant velocity.
Two forces that can hinder momentum?
elastic and inelastic
