The two forces at work when a ball is thrown up into the air are gravity and air resistance.
When a ball is thrown up into the air, the two forces at work are gravity and air resistance.
When a ball is thrown up into the air, two main forces are at work: gravity and air resistance.
1. Gravity: Gravity is the force that pulls objects towards the Earth's center. When the ball is thrown up, gravity acts to pull the ball back down towards the ground. This force is constantly present and acts in a downward direction.
2. Air Resistance: Air resistance, also known as drag, is the force exerted by the air on the moving object. As the ball moves through the air, it encounters resistance due to the air molecules colliding with its surface. In the case of a ball thrown up into the air, air resistance acts in the opposite direction to its motion, slowing it down and eventually causing it to fall back to the ground.
To get this answer, you can rely on your knowledge of the basic forces present in the world or search for information on the forces acting on objects thrown into the air. Sources such as textbooks, scientific articles, or educational websites can provide comprehensive explanations about the forces at work in this scenario.
