Two cars can have equal and opposite momentum if they have different masses. Momentum is the product of mass and velocity, so even if the two cars are traveling at different speeds, their momenta can be equal and opposite as long as their masses are inversely proportional to their velocities.

When an object speeds up it gains momentum true or false?
True. When an object speeds up, its velocity increases, and therefore its momentum also increases. Momentum is the product of an object's mass and its velocity, so an increase in velocity results in an increase in momentum.
Why if total momentum is zero but kinetic energy is not equal to zero?
In a system where the total momentum is zero but the kinetic energy is not zero, it means that the opposing momenta of the individual objects cancel out, resulting in a net zero momentum for the system. However, the objects can still possess kinetic energy due to their individual speeds and masses, which contribute to the overall energy of the system.
Two ice skaters initially at rest have pushed off each other and are moving in opposite directions with equal speeds. What is known about their masses?
Their masses are equal. According to the law of conservation of momentum, the total momentum of the system will remain constant before and after the push-off. Since the two ice skaters have equal and opposite momenta after the push-off, their masses must be equal in order to fulfill this conservation law.
What is the rocket and momentum?
A rocket is a vehicle that uses the principle of momentum to propel itself forward in space. By expelling mass at high speeds in the opposite direction they want to move, rockets generate thrust according to Newton's third law of motion (action and reaction). This allows them to travel through the vacuum of space where there is no air for traditional propulsion methods like airplanes.
Is it true two objects with the same mass will always have the same momentum?
No, two objects with the same mass will not always have the same momentum. Momentum is a vector quantity that depends on both mass and velocity. If the objects are moving at different speeds, they will have different momenta even if they have the same mass.

When an object speeds up it gains momentum true or false?
True. When an object speeds up, its velocity increases, and therefore its momentum also increases. Momentum is the product of an object's mass and its velocity, so an increase in velocity results in an increase in momentum.
Does an object gain momentum when it speeds up?
Yes The equation for momentum is mass x velocity So if you increase velocity the momentum increases
Which ball will have the greater speed at 30 meters per second?
If both balls are travelling at 30m/s, then they have identical speeds, and neither is travelling faster.

Does an object with more momentum have more or less inertia?
An object with more momentum has more inertia. Inertia is the tendency of an object to resist changes in its state of motion, and momentum is directly related to an object's mass and velocity. Therefore, an object with more momentum will have more resistance to changes in its motion.

How long does it take to travel 36 miles?
That would depend on what way you were travelling and how fast you were travelling at. You could be crawling, hopping, walking, swimming, driving, flying, sailing, skiing, cycling etc. You could be doing any of those at different speeds. The terrain you were travelling over could be another factor, as could other things, like weather.That would depend on what way you were travelling and how fast you were travelling at.

Is it true two objects with the same mass will always have the same momentum?
No, two objects with the same mass will not always have the same momentum. Momentum is a vector quantity that depends on both mass and velocity. If the objects are moving at different speeds, they will have different momenta even if they have the same mass.
