ⓒ. It falls back to Earth immediately.
ⓓ. It changes orbit unpredictably.
Correct Answer: It remains in orbit at a constant speed.
Explanation: A satellite orbiting the Earth will remain in orbit at a constant speed unless acted upon by an external force due to inertia. Inertia causes the satellite to continue moving in its current state of motion unless a force (such as gravitational pull) changes its velocity or direction.
97. Why does a coin placed on a spinning record move outward towards the edge as the record spins faster?
ⓐ. Due to gravitational pull
ⓑ. Due to centripetal force
ⓒ. Due to the record’s shape
ⓓ. Due to the coin’s inertia
Correct Answer: Due to the coin’s inertia
Explanation: The coin moves outward towards the edge of the spinning record as it spins faster due to its inertia. The coin tends to remain at rest (or in its initial state of motion), causing it to move outward as the record’s speed increases.
98. What is the primary reason why passengers wear seat belts in vehicles?
ⓐ. To prevent accidents
ⓑ. To comply with traffic laws
ⓒ. To avoid air resistance
ⓓ. To protect against inertia
Correct Answer: To protect against inertia
Explanation: Passengers wear seat belts in vehicles primarily to protect against the effects of inertia. In the event of sudden deceleration or collision, seat belts prevent passengers from continuing to move forward at their initial speed, reducing the risk of injury.
99. Why does a rocket need to overcome inertia to leave Earth’s atmosphere?
ⓐ. To travel at high speeds
ⓑ. To avoid air resistance
ⓒ. To reach escape velocity
ⓓ. To move in a straight line
