When you are in a car, train, or airplane, you can move around comfortably even though the vehicle is hurtling along. It's the same way with the Earth. The surface velocity relative to the center is a bit more than 1,000 mph at the equator, which counters gravity there *slightly*, making Earth an oblate spheroid (flattened at the poles). But everything on the Earth including oceans and atmosphere is spinning along with it. The only noticeable effect is when something moves north or south, there is a small force that curves its path (often called the Coriolis effect). This leads to wind and ocean current patterns, including hurricane direction. Similarly, Earth moves in its orbit at almost 30 km/s (over 100,000 mph!), but since everything is moving with it, we don't notice. Earth's rotational and orbital velocity *does* have to be taken into account when we launch spacecraft, since we need to calculate thrusts and directions relative to whatever the destination is. And you could go beyond the Solar System to note that the Sun is in orbit around the galaxy and the galaxy is speeding toward the Andromeda galaxy, but we are all going along for the ride.
