Investigating Gravity Quick Check

Answer 1

1. What is gravity?

Gravity is the force that attracts objects with mass towards each other.

2. Who discovered gravity?

Sir Isaac Newton is credited with discovering the concept of gravity.

3. How does gravity affect objects on Earth?

Gravity is what keeps objects grounded to the Earth's surface and also determines the weight of objects. It causes objects to fall towards the ground when released.

4. What is the formula to calculate the force of gravity?

The formula to calculate the force of gravity is F = G * (m1 * m2) / r^2, where F is the force of gravity, G is the gravitational constant, m1 and m2 are the masses of the two objects, and r is the distance between the centers of the two objects.

5. How does gravity affect the motion of planets in our solar system?

Gravity is the force that keeps planets in orbit around the sun. It is responsible for the motion of planets within the solar system and plays a crucial role in maintaining the stability of the system.
