* A ball thrown in the air: The ball travels upwards, but gravity constantly pulls it downwards, causing it to slow down until it reaches its highest point and then accelerates back down to the ground.
* A roller coaster: The roller coaster's motion is dictated by gravity. As it climbs hills, gravity slows it down, and as it descends, gravity speeds it up.
* A satellite orbiting the Earth: The satellite is constantly falling towards the Earth due to gravity, but its forward motion is so great that it keeps missing the Earth, causing it to orbit in a circle.
* A car driving on a hill: Gravity pulls the car downwards, causing it to slow down as it drives uphill. On the downhill side, gravity accelerates the car.
* A river flowing downhill: Gravity pulls the water in the river downwards, causing it to flow from higher elevations to lower elevations.
