Right now the ball only has potential energy but when the ball falls that will be converted into kinetic energy because it is moving. BTW Im 14 in 9th grade ya'll should know this.
Answer:
potential; kinetic
Explanation:
Answer:
momentum = mass x velocity
Explanation:
So ultimately, find the mass of the object (be careful since this is not the same as weight. Weight is your gravitational pull to the earth. This means that your weight different amounts on different planets. But mass stays the same on all planets, it's what most people call their weight.) and then find the velocity (2 meters/second north, etc.)
Now you can apply this to your problem
Answer: To help eliminate subjectivity

ultraviolet rays
radio waves
infrared waves
Infrared waves from the electromagnetic spectrum are used in heat lamps and heat sensing devices, as they can penetrate and heat objects more deeply and are also emitted by objects based on their temperature.
The type of waves from the electromagnetic spectrum that are used in heat lamps and heat sensing devices are infrared waves.
These waves are invisible to the human eye but are detectable as heat. Infrared waves have longer wavelengths than visible light, which enables them to penetrate and heat objects more deeply.
For instance, a heat lamp emits infrared radiation that can warm up the objects it shines upon, while heat sensing devices, like thermal cameras, detect the infrared radiation emitted by objects based on their temperature.
