Here are the step-by-step solutions for the questions visible in your worksheet.
Question 1
*
Reasoning: The statement "An object at rest will stay at rest and an object in motion will stay in motion unless acted on by a force" is the definition of the Law of Inertia. This is Newton's
1st Law. The 2nd Law deals with Force = Mass x Acceleration, and the 3rd Law deals with action and reaction pairs. There is no standard "4th Law."
*
Selection: B (1st Law of Motion)
Question 2
*
Reasoning: The tendency of an object to resist changes in its state of motion (like wanting to keep going straight when a car turns) is called
inertia. Drag force and friction are forces that slow things down, but "inertia" is the specific name for the resistance to change itself.
*
Selection: C (inertia)
Question 3
*
Reasoning: When forces are unbalanced, it means they are not equal. The object will always accelerate or move in the direction of the stronger push or pull. Therefore, it moves in the direction of the
larger force.
*
Selection: A (larger)
Question 4
*
Reasoning: The image shows a skateboard with wheels. When round objects like wheels roll over a surface, the type of friction involved is called
rolling friction. Sliding friction happens when you drag something flat (like a box), static friction keeps things stuck in place, and fluid friction happens in water or air.
*
Selection: B (Rolling Friction)
Question 5
*
Reasoning: Fish swim in water. Water is a liquid, which is considered a "fluid" in science. When an object moves through a liquid or a gas, it experiences resistance known as
fluid friction (also often called drag).
*
Selection: Fluid Friction (Option A)
