What Do These Expressions Mean? “It's running” and “it's moving quickly” both describe something that is traveling at high speed on land. They tell someone that an animal, person, or object is going fast. Children say these words about dogs, cars, or children racing. Both describe fast land movement.
“It's running” means moving fast on legs, faster than a walk. A child says it when a dog sprints across the yard. It is specific to leg movement.
“It's moving quickly” means traveling at high speed by any means. A car, a train, a rolling ball. It is more general and formal. It does not specify legs.
These expressions seem similar. Both say “fast.” Both describe speed. But one is for animals and people on legs while one is for any moving object.
What's the Difference? One is for leg-powered movement. One is for any fast movement. “It's running” is for creatures with legs moving faster than a walk. A child, a dog, a horse. It implies a running gait.
“It's moving quickly” is for any object or creature moving fast. A car, a bike, a thrown ball, a rabbit. It is more general. It sounds more formal.
Think of a dog chasing a ball. “It's running” is right. A car on the highway. “It's moving quickly” fits better. One is for legs. One is for any fast thing.
One is for children and animals. The other is for formal or general talk. “Running” for a friend racing. “Moving quickly” for a science experiment. Use the first for play. Use the second for description.
Also, “running” can mean “operating” (the engine is running). “Moving quickly” does not have that meaning. Context matters.
When Do We Use Each One? Use “it's running” for leg-powered, fast movement. Use it for animals, people, or cartoon characters. Use it for play and exercise. It fits active talk.
Examples at home: “The dog is running after the ball.” “Look, my friend is running fast.” “The horse is running in the field.”
Use “it's moving quickly” for any fast object, especially vehicles or machines. Use it for cars, trains, or science experiments. Use it to be general or formal. It fits descriptive talk.
Examples for general speed: “The train is moving quickly.” “The toy car is moving quickly across the floor.” “In the video, the cheetah is moving quickly.”
Children can use both. “Running” for legs. “Moving quickly” for any fast thing. Both describe speed.
Example Sentences for Kids It's running: “It's running away from me!” “The rabbit is running into the woods.” “I am running to the finish line.”
It's moving quickly: “The bus is moving quickly.” “The remote control car is moving quickly.” “The water is moving quickly down the drain.”
Notice “running” is for legs. “Moving quickly” is for anything fast. Children learn both. One for feet. One for everything.
Parents can use both. A friend racing: “he's running.” A train passing: “it's moving quickly.” Children learn different speed descriptions.
Common Mistakes to Avoid Some children say “running” for a car. Cars do not have legs. They drive or move. Say “the car is moving quickly” or “driving fast.”
Wrong: “The car is running.” (can mean the engine is on) Better: “The car is moving quickly.”
Another mistake: saying “moving quickly” for a person running. That is correct, but it sounds odd. A friend running is “running,” not “moving quickly.” Save “moving quickly” for vehicles or formal talk.
Wrong: “The boy is moving quickly.” (strange) Better: “The boy is running.”
Some learners think “running” is only for exercise. Running for the bus is still running. Any faster-than-walk leg movement is running. Use it freely.
Also avoid saying “it's running” for a machine that is not moving. “The engine is running” means it is on, not moving. That is a different meaning.
Easy Memory Tips Think of “running” as sneakers on a track. Feet lifting. Fast pace. For legs.
Think of “moving quickly” as a speedometer needle. High number. Fast. For any fast thing.
Another trick: remember the body part. “Running” uses legs. “Moving quickly” uses anything. Legs get “running.” Anything gets “moving quickly.”
Parents can say: “Run for a foot. Quickly for a jet to boot.”
Practice at home. A runner: “it's running.” A car: “it's moving quickly.”
Quick Practice Time Let us try a small exercise. Choose the better phrase for each situation.
A child watches a rabbit sprint across the grass. a) “It's moving quickly.” b) “It's running.”
A child watches a remote control car zip across the floor. a) “It's running.” b) “It's moving quickly.”
Answers: 1 – b. A rabbit on legs running fits the leg-specific “running.” 2 – b. A wheeled toy fits the general “moving quickly.”
Fill in the blank: “When I see my friend racing me to the tree, I say ______.” (“It's running” is the leg-powered, active, playful choice.)
One more: “When I see a roller coaster zoom down the track, I say ______.” (“It's moving quickly” fits the vehicle, wheeled, general-speed description.)
Speed is exciting. “It's running” cheers for legs. “It's moving quickly” notes fast objects. Teach your child both. A child who learns both sees speed everywhere.
Wrap-up “It's running” describes fast, leg-powered movement of people, animals, or anything with legs moving faster than a walk. “It's moving quickly” describes any object or creature traveling at high speed, including vehicles, machines, and rolling objects. Use “it's running” for dogs, kids, and rabbits. Use “it's moving quickly” for cars, trains, and fast-moving objects. Both phrases describe speed on land. A child who learns both can tell you if something is running on legs or just moving fast.
