Yes, an increase in afterload (pressure the heart must pump against to eject blood) typically causes the heart to work harder to overcome this resistance, leading to increased cardiac workload. This can result in the heart needing to pump with more force to maintain adequate blood flow to the body.
Work is directly proportional to both force and distance. As force increases, the work done will also increase. Likewise, if the distance over which the force is applied increases, the work done will also increase proportionally.
If force increases and distance remains the same, the amount of work done would increase. This is because work done is directly proportional to the force applied. The formula for work is Work = Force x Distance, so as force increases, work done would also increase.
When work is done on a system by pushing it, the internal energy of the system increases, leading to an increase in temperature. The work done increases the kinetic energy of the particles in the system, causing them to move faster and leading to an increase in temperature.
An increase in force applied to an object will result in an increase in the amount of work done on the object. This is because work is directly proportional to force – as force increases, so does the amount of work done.
If force increases by 5 times, then work will also increase by 5 times, assuming the displacement remains constant. This is because work is directly proportional to the force applied.
By relaxing the blood vessels, antiangina drugs reduce the heart's work load and increase the amount of oxygenrich blood that reaches the heart.
It's all about the conservation of energy, and the fact that you don't get something for nothing! As a generator's load increases, the current through the machine increases, so more work has to be done to overcome the resulting increase in 'motor action' caused by the load current. As work is the conversion of one form of energy into another, then more energy must be supplied -and that energy is provided by the fuel supplied to the prime mover.
Reduces the work load and increases cardiac output
Work is directly proportional to both force and distance. As force increases, the work done will also increase. Likewise, if the distance over which the force is applied increases, the work done will also increase proportionally.
It increases it and causes the heart to work harder.

When work is done on a system by pushing it, the internal energy of the system increases, leading to an increase in temperature. The work done increases the kinetic energy of the particles in the system, causing them to move faster and leading to an increase in temperature.
when you exercise, the heart rate increases, (as does your breathing pace), so that more oxygen can be carried in the blood to your muscles. The more intense the exercise, the more your muscles have to work, so more oxygen is required and your heart rate will increase. The quicker you heart rate returns to normal, the better your fitness.
An increase in force applied to an object will result in an increase in the amount of work done on the object. This is because work is directly proportional to force – as force increases, so does the amount of work done.
No, exercise doesn't increase the size of the heart. Exercise does strengthen the heart so that you can become more active in life.
With a third class lever, the input force is located between the fulcrum and the load. They increase the distace the load is carried.
It decreases because your heart no longer has to work as hard.
