  • Question 1
    1 / -0
    As longer the interaction between two objects exist:
    Solution
    A force is a push or pull on an object. This push or pull comes from the objects interacting with one another and only from such interactions. Once the interaction stops, there is no longer any force.
  • Question 2
    1 / -0
    Fill in the blank.
    At least ___________ objects must interact for a force to come into play. 
    Solution
    $$Answer:-$$ B 
    Pushing, hitting and pulling of objects are all ways of bringing objects in motion. This friction force arises between two surfaces in contact. No motion of the wood (in fig) will take place if it is at rest and equal forces in both direction are applied, but no net force is needed to sustain the uniform motion of the marble.
    By newtons third law: For every action, there is an equal and opposite reaction. So two forces come into picturure for action.

  • Question 3
    1 / -0
    Which of the following is/are contact forces
    Solution
    Contact forces are those types of forces which result when the two interacting objects are perceived to be physically contacting each other. Examples of contact forces include frictional forces, tensional forces, normal forces, air resistance forces, and applied forces.
  • Question 4
    1 / -0
    Suppose a man is standing behind a stationary car. Which of the following options will be correct?
    Solution
    The interaction of one object with another object results in a force between the two objects. If a man is standing behind a stationary car,  there is no interaction between the man and the car, So no force act on the car, and hence the car does not move.
  • Question 5
    1 / -0
    Mark the correct option.
    Solution
    $$Answer:-$$ B
    Pushing, hitting and pulling of objects are all ways of bringing objects in motion. This friction force arises between two surfaces in contact. No motion of the wood (in fig) will take place if it is at rest and equal forces in both direction are aplied, but no net force is needed to sustain the uniform motion of the marble.
    By newtons third law: For every action, there is an equal and opposite reaction. So two forces come into picturure for action.

  • Question 6
    1 / -0
    Pulling of a cart/tram is an example of
    Solution
    Contact force is a force that is applied by objects in contact with each other. Since, pulling of cart requires a force applied in contact with the cart. Hence, this is an example of Contact force.

  • Question 7
    1 / -0
    Mark the correct option
    Solution
    Force acting on a body can change its state of rest or of motion.

    A force can make a stationary object move-when you kick a stationary football, it moves.

    A force can stop a moving object when a force is applied opposite to the direction of motion. And force increases the speed of the moving object when applied along with the motion.
  • Question 8
    1 / -0
     Fill in the blank.
    Interaction of one object with ________ results in a force.
    Solution
    $$Answer:-$$ B
    The best example we can take into account is the gravitational force.
    Gravitation or gravity is a natural phenomenon by which all things with mass are brought toward one another, including planets, stars, and galaxies.

  • Question 9
    1 / -0
    Force that enables us to perform all activities like movement or bending of the body is
    Solution
    It is the muscular force that enables us to perform all activities involving movement or bending of our body. It is the force resulting due to the action of muscles. Our muscles generate this force by the contraction and relaxation.
  • Question 10
    1 / -0
    $$2 \ N$$ force is applied on a body from the right side and $$6 \ N$$ is applied from the left side .The resultant force will be __________ $$N$$
    Solution
    If two forces act in the opposite directions on an object, the net force acting on it is the difference between the two forces. The direction of the net force is in the direction of the larger force.
    Force 1 $$F_1=-2 \ N$$ (towards left)
    Force 1 $$F_2=+6 \ N$$ (towards right)

    Resultant force $$F_1+F_2=-2N + 6 N =+4 N$$ (towards right)
