Force is a
The strength of force is expressed by
The force between two charged bodies is called
The electric force between two charged bodies at rest is conventionally called electrostatic force or Coulomb force.
When two forces act in opposite directions, then net force acting is the
State of motion is described by
Magnetic force is
Magnetic forces are non - contact forces; they pull or push on objects without touching them. Magnets are only attracted to a few 'magnetic' metals and not all matter.
Force acts on an object may change
The net force on an object is zero if the two forces act on it in
Leaves or fruits fall on the ground due to
Otto von Guericke was a scientist of
Force of friction is an example of non-contact force.
If two forces act in opposite directions on an object, the net force is the difference between the two forces.
The force of friction can be reduced by using lubricants.
A lubricant is a substance, usually organic, introduced to reduce friction between surfaces in mutual contact, which ultimately reduces the heat generated when the surfaces move. It may also have the function of transmitting forces, transporting foreign particles, or heating or cooling the surfaces.
The force exerted per unit area is called magnitude.
The correct answer is B as force exerted per unit area is called pressure.
A force can change the state of motion of an object.
If the force applied on the object is in the direction of its motion, the speed of the object increases. If the force is applied in the direction opposite to the direction of motion, then it results in a decrease in the speed of the object. Thus, a force may bring a change in the state of motion of an object.
Muscular force is a kind of contact force.
Force of gravity is contact force.
At least two objects must interact for a force to come into play.
Pascal is the unit of force.
The Pascal is the Si unit of Pressure. Whereas the Si unit of force is Newton.
So, the given statement is false.
To move an object faster it has to be pushed or pulled repeatedly.
To move an object faster it has to be pushed or pulled repeatedly.
Pull:- Applying force in a direction towards us is known as pull.
Push:- Applying force in a direction away from us is known as push.
