### Answer the following question using the diagram.If the car travels once around the racetrack, what distance does it travel?

• A.

100 m

• B.

0 m

• C.

200 m

• D.

50 m

A. 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.

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

• A.

100 m

• B.

0 m

• C.

200 m

• D.

50 m

C. 200 m
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.

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

• A.

100 m

• B.

0 m

• C.

200 m

• D.

300 m

B. 0 m
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.

### Momentum is defined as

• A.

Mass X Velocity

• B.

Mass X acceleration

• C.

Mass X Force

• D.

None of these

A. Mass X Velocity
Explanation
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.

### "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

• A.

Newton's First law of motion

• B.

Newton's Gravitational law

• C.

Newton's second law

• D.

Newton's third law

• E.

Newton's fourth law

A. Newton's First law of motion
Explanation
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.
