Newton's Laws, inertia, weight, etcThis is your description.


Questions and Answers
  • 1. 

    A push or a pull is called a ______________ and is measured in _________________.

    • A.

      Weight; kilograms

    • B.

      Force; kilograms

    • C.

      Weight; pounds

    • D.

      Force; newtons

    Correct Answer
    D. Force; newtons
    Explanation
    A push or a pull is referred to as a force and is measured in newtons. Force is a vector quantity that describes the interaction between objects and can cause them to accelerate or change direction. Newtons is the standard unit of force in the International System of Units (SI). Weight, on the other hand, is the force experienced by an object due to gravity and is typically measured in pounds or kilograms. Therefore, the correct answer is force; newtons.

    If a force of 50N acts on a 5 kg object, its acceleration is equal to ______ meters per second squared.

    • A.

      55

    • B.

      45

    • C.

      250

    • D.

      10

    Correct Answer
    D. 10
    Explanation
    The acceleration of an object is equal to the force acting on it divided by its mass. In this case, the force acting on the 5 kg object is 50N. Dividing 50N by 5 kg gives us an acceleration of 10 meters per second squared.

    A body at rest tends to stay at rest is called _______________,

    • A.

      Equilibrium

    • B.

      Newton's first law

    • C.

      Newton's second law

    • D.

      Newton's third law

    Correct Answer
    B. Newton's first law
    Explanation
    Newton's first law states that a body at rest tends to stay at rest, and a body in motion tends to stay in motion with the same speed and in the same direction unless acted upon by an external force. This law is also known as the law of inertia. It explains the concept of equilibrium, where an object will remain in its current state unless a force is applied to it. Therefore, the correct answer is Newton's first law.

    To find the horizontal force acting on an object that is being pulled by a rope at an angle of 50 degrees with the ground, you would use ______________.

    • A.

      The Pythagorean theorem

    • B.

      Sine

    • C.

      Cosine

    • D.

      Tangent

    Correct Answer
    C. Cosine
    Explanation
    To find the horizontal force acting on an object being pulled by a rope at an angle of 50 degrees with the ground, we would use cosine. The cosine function relates the adjacent side of a right triangle to the hypotenuse. In this case, the adjacent side represents the horizontal force we are trying to find, and the hypotenuse represents the total force being applied by the rope. By using cosine, we can calculate the horizontal force accurately.

    The resistance an object has to a change in its motion is called ______________,

    • A.

      Equilbrium

    • B.

      Inertia

    • C.

      Momentum

    • D.

      Drag

    Correct Answer
    B. Inertia
    Explanation
    Inertia is the correct answer because it refers to the resistance an object has to a change in its motion. This means that an object at rest will stay at rest, and an object in motion will continue moving at a constant velocity unless acted upon by an external force. Inertia is a property of matter and is directly related to an object's mass. The greater the mass, the greater the inertia, and the more difficult it is to change the object's motion.
