Question

an apple is on a tree. a few seconds later, the apple falls down from the tree and hits the ground. later, the apple is on the ground. 8. what is the force that pulls objects towards the ground on earth? 9. the apple is on the tree and it is not moving. what are the two types of forces acting on the apple? 10. the apple is falling down and accelerating. what are the two types of forces acting on the apple? 11. the apple is on the ground and it is at rest. what are the two forces acting on the apple?

Explanation:

Question 8

The force that pulls objects towards the Earth's ground is gravity (or gravitational force). This is a fundamental force in physics where the Earth exerts an attractive force on objects near its surface.

When the apple is on the tree and not moving, two forces act on it: gravity (pulling it downwards) and the tension/normal force from the tree branch (pulling it upwards, balancing gravity). These two forces are equal in magnitude and opposite in direction, resulting in a net force of zero (equilibrium).

As the apple falls and accelerates, gravity pulls it downwards, and air resistance (a type of frictional force) acts upwards, opposing the motion. Since the apple is accelerating, the gravitational force is greater than the air resistance force.

Answer:

Gravity (or Gravitational Force)
