Could you give me 4 examples of acceleration?

Certainly.

1). A driver presses the gas and the car speeds up.

2). A driver presses the brake and the car slows down.

3). A driver turns the steering wheel slightly. The car's speed doesn't change

as it goes around the curve.

4). A stone is tossed into the air. Gravity accelerates it from the moment it

leaves the thrower's hand until it hits the ground.

5). A new TV satellite is successfully launched and placed in a perfect circular

orbit around the Earth. The satellite's motion is accelerated forever, 24/7/365.

"Acceleration" means any change in the speed or direction of motion. Any

object that's not moving at constant speed in a straight line is accelerated.
