The interaction of forces can also be thought of as a push or a pull. A change in the state of motion corresponds to either a change in the speed of the body and/ or a change in the direction of motion of the body. The change in speed could mean speeding up (acceleration) or speeding down (deceleration). A ball cannot move on its own, and ...
- Force is pushing or pulling any object resulting from the object’s interaction with another object. Without force, nothing can be moved, stopped or...
- According to Newton’s second law of motion, we know that force is a product of mass and acceleration. When a force is applied to the rocket, the fo...
- There are two types of forces: Non-contact forces Contact forces
- Contact forces are the forces that occur due to the contact between two different objects.
- A non-contact force is a force applied to an object by another body that is not in direct contact with it. Non-contact forces come into play when o...
The 3 common shape changing forces. 1. Squeezing or crushing a drink-can: two forces are involved, acting inwards onto the object; we call these forces "compression forces". 2. Stretching a blob of blu-tac or a rubber band: two forces are involved, acting outwards from the object; we call these forces "tension forces".

Kick a ball and it'll fly up into the air beforefalling back down to the ground. That's an example of everydayforces. What exactly is a force? Kicking a ball involves you applying a force (a push with your foot)that makes it fly upward. But once it's shooting through the air, theinvisible force of gravitypulls it back down to Earth—and that's adiff...
When we're looking at how things work or move, wetry to identify the force that's responsible. So when a flying ballzooms to the ground, we say "Aha! That's the force of gravity."But it's very rare to find only one force acting on something. Mostof the time, there are several different forces working at once, allpulling or pushing with different st...
When a force acts on an object, it often makes itmove faster or in a different direction. Once something is moving,you don't need a force to keep it moving: it will carry on moving allby itself unless another force stops it. When a rocketblasts intospace, you need a force to make it lift off to begin with and toovercome the force of Earth's gravity...
It takes a force to make something move in adifferent way, and that includes changing the direction in whichsomething is moving even if its speed stays the same. If you want tomake something go round in a circle, you have to apply a force tomake it turn and keep on applying that force to keep it turning. Thatmakes sense: something moving in a circl...
Forces make things move—but they also bringmoving things to a halt. Roll a toy car over a rug and it'll quicklycome to a standstill. The force of frictionsteals the car'senergy and slows it down. Friction is the force between two differentobjects that are in contact, either when they're locked together andtouching or when one of them slides past th...
Have you ever tried tugging the aluminum ring-pull of adrinks can and found it suddenly snaps off in your hand? What you'retrying to do is use a force to make the ring-pull move and changedirection at the same time. But instead of doing what you expect, onepart of the ring-pull snaps away from the other. This is an exampleof how forces can change a...
Aug 17, 2022 · Permanent changes can mean that the object is destroyed. An example of a permanent change caused by forces is a bridge that collapses and can no longer carry the weight of moving vehicles and pedestrians. Temporary changes of shape . Some materials can change shape depending on the amount of force applied to them.
The particles within the object are pulled apart from each other, causing the overall shape of the object to change. Conversely, if the force is applied in a direction that pushes the object together, it can cause the object to compress. This is commonly seen in objects like balls or cushions when pressure is applied. The particles within the ...
Effects of Forces Explained. A force acting on an object, causes the chosen object to change its size and shape to start moving or decelerate and accelerate. When there’s an interaction between two objects, they exert a force on each other. We can say that these exerted forces are equal in size but opposite in direction.

Forces can change the shape of an object. Depending on the object, the change in shape may be temporary or permanent. An object that returns to its original shape once the force is no longer acting on it is known as an elastic object. An object that retains its new shape once the force is no longer acting on it is known as an inelastic object ...
