What is the difference between rate of climb and climb gradient? I am currently trying to study aircraft performance and I have some difficulties distinguishing between rate of climb and climb gradient.

Can someone explain what are the differences between the two of them?
The climb gradient is the percentage of the rise over run (100% if you are climbing at 45 degrees) that your aircraft is climbing at while the rate of climb is the speed at which you are climbing based off the airspeed and climb gradient (given in feet per minute).
