1. Answer the following question using the diagram.

If the car travels once around the racetrack, what distance does it travel?

100 m

0 m

200 m

50 m

The diagram shows a racetrack with a complete loop. If the car travels once around the racetrack, it will cover the entire distance of the loop, which is 100 meters. Therefore, the correct answer is 100 m.

Explanation

The diagram shows a racetrack with a complete loop. If the car travels once around the racetrack, it will cover the entire distance of the loop, which is 100 meters. Therefore, the correct answer is 100 m.

2.

If the car travels twice around the racetrack, what distance does it travel?

100 m

0 m

200 m

50 m

If the car travels twice around the racetrack, it covers the distance of one lap twice. Therefore, the total distance traveled by the car is 200 meters.

Explanation

If the car travels twice around the racetrack, it covers the distance of one lap twice. Therefore, the total distance traveled by the car is 200 meters.

3. "A body continues in its state of rest or uniform motion in a straight line unless acted upon by a force" is a statement of

Newton's First law of motion

Newton's Gravitational law

Newton's second law

Newton's third law

Newton's fourth law

This statement is known as Newton's First Law of Motion, also referred to as the law of inertia. It states that an object at rest will remain at rest, and an object in motion will continue moving in a straight line at a constant velocity unless acted upon by an external force. This law describes the concept of inertia, which is the tendency of an object to resist changes in its motion.

This law describes the concept of inertia, which is the tendency of an object to resist changes in its motion.

4. Momentum is defined as

Mass X Velocity

Mass X acceleration

Mass X Force

None of these

Momentum is defined as the product of an object's mass and its velocity. It is a vector quantity, meaning it has both magnitude and direction. The greater the mass or velocity of an object, the greater its momentum. Acceleration and force are not directly related to momentum, although they can affect it indirectly through changes in velocity. Therefore, the correct answer is Mass X Velocity.

Momentum is defined as the product of an object's mass and its velocity. It is a vector quantity, meaning it has both magnitude and direction. The greater the mass or velocity of an object, the greater its momentum. Acceleration and force are not directly related to momentum, although they can affect it indirectly through changes in velocity. Therefore, the correct answer is Mass X Velocity.

5.

If the car travels thrice around the racetrack, what is its displacement?

100 m

0 m

200 m

300 m

If the car travels thrice around the racetrack, its displacement would be 0 meters. Displacement is a vector quantity that represents the change in position of an object. Since the car starts and ends at the same position after completing three laps, its overall change in position is zero. Therefore, the displacement is 0 meters.

Explanation

If the car travels thrice around the racetrack, its displacement would be 0 meters. Displacement is a vector quantity that represents the change in position of an object. Since the car starts and ends at the same position after completing three laps, its overall change in position is zero. Therefore, the displacement is 0 meters.
