Here are the answers to your questions:
Question 1: When a soccer ball is at rest on the ground, what are the balanced forces that are acting on it?
- Correct Response: Normal force is pushing up on the soccer ball and the Gravitational force is pulling down on the soccer ball.
Question 2: A force of 100 N to the right is applied to a soccer ball when it is kicked. An opposite force of 5 N to the left is applied to the soccer ball due to the friction of the grass. What is the net force applied to the object?
- Correct Response: 95 N to the right
Question 3: When the soccer ball is moving through the air to the right, what is the main force that is acting on the ball, causing it to slow down?
- Correct Response: Air Resistance (drag or fluid friction)
Question 4: When the soccer ball comes in contact with the ground it bounces back up. Why does that happen?
- Correct Response: The ground pushes back with equal force but in the opposite direction. The ball bounces because the mass of the ball is less than the mass of the Earth.
