1. Which of the following best describes centripetal force?
A force that pulls an object away from the center of a circular path.
A force that acts perpendicular to the velocity of an object, keeping it in a circular path.
A force that is always directed tangentially to the circular path.
A force that causes an object to move in a straight line.
2. According to Newton's Law of Universal Gravitation, the gravitational force between two objects is directly proportional to:
The distance between their centers.
The square of the distance between their centers.
The product of their masses.
The square of their masses.
3. The acceleration experienced by an object moving in a circular path is called acceleration.
4. The force that causes planets to orbit the sun is .
5. Centripetal force always acts towards the center of the circular path.
True
False
6. The value of the gravitational constant (G) depends on the masses of the objects involved.
True
False
7. State the formula for centripetal force and define each variable.
8. Explain the difference between mass and weight.
9. A car of mass 1200 kg is turning a corner with a radius of 25 meters at a speed of 10 m/s. Calculate the centripetal force acting on the car.
10. Two objects, each with a mass of 50 kg, are separated by a distance of 2 meters. Calculate the gravitational force between them. (G = 6.67 × 10^-11 N⋅m²/kg²)
