types of forces

name the types of forces

• Soft force, Hard force, Smooth force, and Rough force
• Positive force, Negative force, Neutral force, and Opposite force
• Heat force, Light force, Sound force, and Electric force
• Gravitational force, magnetic force, frictional force and muscular force

• Push force, Pull force, Twist force, and Bend force

what is frictional force

• Force that changes the direction of an object's motion
• Force that has no effect on the motion of an object
• Force that comes in play when two object is rubed against each other

• Force that helps the motion of an object

what is Muscular force

• The force generated by the contraction of tendons.
• The force generated by the expansion of muscles.
• The force generated by the movement of bones.
• it playes when we lift , push and bend

what is a contact force

• A force that acts at a distance between two objects
• a contact force happens when 2 forces act together example frictional force and gravitational force

• A force that only affects one object
• A force that is not related to the point of contact between two objects

how is contact force different from non - cotact force

• Contact force is always attractive, while non-contact force is always repulsive
• Contact force only occurs in outer space, while non-contact force only occurs on Earth
• Contact force acts at the point of contact between two objects, while non-contact force acts at a distance without any physical contact.
• Contact force is imaginary, while non-contact force is real

what is non - contact force

• A force that only affects living organisms
• it can be applied on objects from a distance

• A force that is always attractive in nature
• A force that requires direct physical contact with an object
• A force that can only be exerted by humans

what makes thing fall down when we drop it from a height

why is it easy for us to walk down a stairs but is difficult to walk up stairs

• Lack of exercise
• Weak leg muscles

  is the problem to walk up stairs

• Fear of heights makes it hard to walk stairs

• Gravity makes it hard to walke stairs

what is magnetic force

• The force exerted by gravity on a magnetic object
• The force exerted by electricity on a magnetic object
• The force exerted by wind on a magnetic object
• magnetic force is when a magnet or a object is pulling some thing towards it

for what do we use magnets in our daily life

• to hid things

• we use it for nothing

• to find or take medal object like a spoon stuck between or under something

• to stick sticky notes on a refrigerator

• all of the above
