Forces and Motion
|
|
Motion- Motion is the movement of objects from one location to another.
The motion of an object can change by speeding up, slowing down or changing direction.
Forces- Everything—anything—that pushes, pulls, squeezes, stretches ,or twists. Forces are responsible for all changes in the motion of objects. Whenever an object speeds up, slows down, or changes direction, a force must have been involved.
Forces cause changes in motion.
If a force is applied in the same direction of an object’s motion, the speed will increase.
If a force is applied in the opposite direction of an object’s motion, the speed will decrease.
The greater the force acting on an object, the greater the change in motion.
The more weight an object has, the less influence a given force will have on its motion.
If no forces act on an object, the object does not change its motion and moves at constant speed in a given direction.
Any change in speed or direction of an object requires a force and is affected by the weight of the object and the amount of force applied.
Speed is "how fast an object is moving." Speed can be thought of as the rate at which an object covers distance.
*A fast-moving object has a high speed and covers a large distance in a short amount of time.
*A slow-moving object that has a low speed; it covers a relatively small amount of distance in the same amount of time.
*An object with no movement at all has a zero speed.

Everything is affected by forces (pushing, pulling, magnetism, friction and gravity). Explore these sites to understand your world and what controls it a little bit better.
Forces
Friction |
Without friction, our lives would be entirely different. We need it pick things up (thanks to our fingerprints), drive our cars, and something as easy as walking. Explore these sites to learn more about this important force in our lives.

Magnetism
Magnetism is also important in our lives and our world. Actually, our world is a giant magnet with a North and South pole (just like a bar magnet). Without magnetism we would not have electricity to power all the those important electronic devices we depend on so much-computers, televisions, lights....

Gravity
Imagine the world without gravity. How could we eat our food, sleep in our beds at night, or even walk down the hall at school? Many factors go into how much gravity is here on Earth, but do you think it's the same everywhere in the Universe? HMMMM....very interesting.
