What is the relation between torque and angular momentum?
Torque is the rate of change of angular momentum.
Which one of the following quantities corresponds to the rate of change of momentum?
Force. The way Newton specified his law originally, force is equal to the derivative of momentum with respect to time (dp/dt) - that is, to its rate of change.
What is the relationship between force an momentum?
According to Newton's second law, the rate of change of momentum of an object is directly proportional to the net force that is acting on that object.
How do forces cause a change in an object's momentum?
A force acting on a body causes acceleration. Acceleration is measure of the rate of change in the object's velocity. As its velocity changes, its momentum, which is the product of its mass and velocity, will change.
Which physical quantity is measured by rate of change of momentum?
Force and rate of change of momentum (both vector quantities) are cause (force) and effect (rate of change of momentum). Newton's second law of motion equates the two quantities, but they are not identical. There is a distinction in that forces derive from interactions between objects (gravitational, electrical, magnetic...) while momentum changes in response to the net force acting on an object or system.
What is the relation between torque and angular momentum?
Torque is the rate of change of angular momentum.
Which of these is the rate of change in velocity momentum speed friction or acceleration?
The rate of change in velocity is called acceleration.
Which one of the following quantities corresponds to the rate of change of momentum?
Force. The way Newton specified his law originally, force is equal to the derivative of momentum with respect to time (dp/dt) - that is, to its rate of change.
What is the rate of change from the ball leaving the ground to its landing position?
Rate of change of what? its mass, location, velocity, momentum, colour, temperature?
What is the relationship between force an momentum?
According to Newton's second law, the rate of change of momentum of an object is directly proportional to the net force that is acting on that object.
How can you relate the force with the change of momentum of a body?
Newton's Second Law was originally formulated as: F=dm/dt. That is, the force is proportional (or equal, if the correct units are used) to the rate of change of momentum. The more force, the faster will the momentum change.
What is rate of change?
Rate of change is often used when speaking about momentum, and it can generally be expressed as a ratio between a change in one variable relative to a corresponding change in another. Graphically, the rate of change is represented by the slope of a line.
How do forces cause a change in an object's momentum?
A force acting on a body causes acceleration. Acceleration is measure of the rate of change in the object's velocity. As its velocity changes, its momentum, which is the product of its mass and velocity, will change.
Can you find the examples when the rate of change of momentum reduces?
Ok, we know that momentum is mass*velocity. To create a change we need to either change velocity or mass. This is where elastic and inelastic collision come into place. Rate of momentum changes in both collision cases. To reduce the rate of change of momentum, even though this is a little vague, you'll need to reduce the changes in either mass or velocity. Such that the momentum at point A, for instance, reduces momentum at point B and then C and so forth (by constantly reducing velocity). A live example is gas molecules, they have numerous collisions and the momentum constantly changes by variation in velocities. But remember the momentum of a system is conserved, that's a thing you'd probably need to know too to understand. Hope that helps.
