What factors affect momentum?
What two factors affect an object’s momentum.
Momentum is affected by the mass of the object and its velocity (or speed).
Momentum is mass in motion!.
Which object has the greatest acceleration?
Object C has the greatest acceleration. It is the only object with an acceleration. Accelerated motion on a p-t graph is represented by a curved line.
Does momentum depend on direction?
Notice that momentum does not just depend on the object’s mass and speed. Velocity is speed in a particular direction, so the momentum of an object also depends on the direction of travel. This means that the momentum of an object can change if: the object speeds up or slows down.
Does momentum depend on inertia?
Momentum is a vector quantity as it the tendency of a body to remain in motion. Inertia is a scalar quantity as it is the resistance offered by the body to any change in its velocity. … Momentum depends on mass and velocity. Inertia depends only on mass.
Do heavier objects fall faster?
Galileo discovered that objects that are more dense, or have more mass, fall at a faster rate than less dense objects, due to this air resistance.
Why does force equal mass times acceleration?
Acceleration is a change in velocity. Newton found that an unbalanced force is required to change an object’s velocity. … The 2nd law provides the definition of force: F = m a, where F is force, m is the mass, and a is acceleration.
How does momentum relate to acceleration?
Momentum Conservation and Newton’s Laws Recall that acceleration is rate of change of velocity, so we can rewrite the Second Law: … rate of change of momentum = mass x rate of change of velocity. This means that Newton’s Second Law can be rewritten: force = rate of change of momentum.
Why is acceleration inversely proportional to mass?
As we increase the force on an object the acceleration increases proportionally. Since the mass does not change as the acceleration increases, we can say that force is equal to acceleration. … Therefore, mass is inversely proportional to acceleration.
Does acceleration affect momentum?
Acceleration is the change in velocity over time. An object that is accelerating, therefore, has an increasing velocity and increasing momentum.
What does the amount of momentum depend on?
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.
Does mass affect acceleration?
Increasing force tends to increase acceleration while increasing mass tends to decrease acceleration. Thus, the greater force on more massive objects is offset by the inverse influence of greater mass. Subsequently, all objects free fall at the same rate of acceleration, regardless of their mass.
In what direction is acceleration if an object is slowing down?
According to our principle, when an object is slowing down, the acceleration is in the opposite direction as the velocity. Thus, this object has a negative acceleration. In Example D, the object is moving in the negative direction (i.e., has a negative velocity) and is speeding up.
How Can acceleration be calculated?
Acceleration (a) is the change in velocity (Δv) over the change in time (Δt), represented by the equation a = Δv/Δt. This allows you to measure how fast velocity changes in meters per second squared (m/s^2). Acceleration is also a vector quantity, so it includes both magnitude and direction.
Does momentum depend on force?
Knowing the amount of force and the length of time that force is applied to an object will tell you the resulting change in its momentum. They are related by the fact that force is the rate at which momentum changes with respect to time (F = dp/dt).
