Acceleration

Acceleration is when you start going faster, like when you get in your toy car and push the pedal to go forward. When you do that, your car starts moving faster and faster until you reach your top speed.

But if you want to stop your car, you push a different pedal to slow down. This is called deceleration, and it's the opposite of acceleration.

The cars you see on the road have special machines called engines, which help the car go faster or slower. When we press the gas pedal, the engine makes the car go faster because it creates more energy to move the car forward.

The more energy the engine makes, the faster and quicker the car will go. That's why some cars like sports cars can go really fast because they have bigger and better engines that create more energy for acceleration.

In conclusion, acceleration is when something starts moving faster and faster and is caused by an engine or a force.
