Here are some easy definitions for Stress/Load and Performance testing.

Stress Testing: Stress Testing is done in order to check when the application fails by reducing the system resources such as RAM, HDD etc. and keeping the number of users as constant.

Load Testing: Load Testing is done in order to check when the application fails by increasing the number of users and keeping the system resources as constant.

Performance Testing: The term Performance can mean measuring response time, throughput, resource utilization, or some other system characteristic( or group of them), by varying the number of users.

Now I know u’ll not forget them 😉
