How does the change in momentum over time affect the motion of an object?
The change in momentum over time affects the motion of an object by determining how quickly the object speeds up or slows down. If the momentum changes rapidly, the object will accelerate or decelerate quickly. If the momentum changes slowly, the object will change its speed more gradually.
Why is Momentum is conserved yet objects slow down after collision this is because of?
Momentum is conserved in a closed system, meaning the total momentum before and after a collision remains the same. In a collision, momentum is transferred between objects, causing their individual velocities to change. While the total momentum remains constant, the distribution of momentum among the objects may change, resulting in some objects slowing down after a collision.
What does it mean to say momentum slowed down?
When momentum slows down, it means that the object's speed or direction of motion is decreasing. This could be due to external forces acting upon the object, causing it to lose its forward motion.
Which of these changes as the momentum of an object changes?
The velocity of an object changes as its momentum changes. Momentum is equal to mass times velocity, so when the velocity of an object changes, its momentum changes proportionally.
What is a force that slows objects down when they rub againts each other?
Friction is the force that slows down objects when they rub against each other. It opposes the motion of objects, resulting in a loss of kinetic energy in the form of heat.
What forces govern thrown objects?
Momentum- a moving object tends to keep moving. Friction- pushing air out of the way slows it down. Gravity- pulls it down
Which force slows down moving objects?
friction
What fluid friction slows objects down?
Drag.
What is the force that slows moving objects down?
friction

How does a vacuum affect the rate at which objects fall?
It slows them down

What does friction do to the motion of object?
Friction slows down the motion of objects.
What is the effect on friction on moving objects?
It resists the motion (slows it down)
What is a force that slows objects down when they rub againts each other?
Friction is the force that slows down objects when they rub against each other. It opposes the motion of objects, resulting in a loss of kinetic energy in the form of heat.
What is an unbalanced force that slows down moving objects?
An unbalanced force that slows down moving objects is called a frictional force. Friction opposes the motion of objects and causes them to slow down due to interactions between the surfaces in contact.
