Hi! I just want to make sure my answers are correct.

(Key: * means that is my answer.)

A basketball momentarily changes shape as it bounces off the floor. This is due to balanced forces on the ball.

True
False*

A ball slowing down as it rolls across the carpet is an example of

Balanced force
Friction*
Inertia
Zero net force

If the net force acting on a wooden object is 0 N, the shape of the object

Will not change*
Changes permanently
Changes temporarily
Reacts to unbalanced forces

Thank you!! Quick answers are appreciated :)

1. A basketball momentarily changes shape as it bounces off the floor. This is due to balanced forces acting on the ball.

B) False

2. A ball slowing down as it rolls across a carpet is an example of?
B) friction

3. Which of the following is causing the net to change shape in the image below?
A) the force of the soccer ball on the net

4. If the net force acting on a wooden object is 0 N, the shape of the object?
A) will not change

don't know if you've seen video of a bouncing ball, but the bottom side flattens to provide the push for the bounce

hi guys! ima bit confused, cus im taking the same quick check, but it has 5 questions

Hi! Let's go through your answers to make sure they are correct:

1. A basketball momentarily changes shape as it bounces off the floor. This is due to balanced forces on the ball.
Your answer: False
Explanation: The correct answer is False. When a basketball bounces off the floor, the shape momentarily changes due to unbalanced forces, not balanced forces. The impact with the floor creates an unbalanced force that causes the basketball to deform before returning to its original shape.

2. A ball slowing down as it rolls across the carpet is an example of
Your answer: Friction
Explanation: The correct answer is Friction. When a ball rolls across a carpet, the force of friction acts in the opposite direction of its motion, causing it to slow down. Friction is a force that opposes the motion between two surfaces in contact.

3. If the net force acting on a wooden object is 0 N, the shape of the object
Your answer: Will not change
Explanation: Your answer is correct. When the net force acting on an object is zero (0 N), it means that the forces acting in one direction are equal to the forces acting in the opposite direction, resulting in a state of equilibrium. In this case, the wooden object's shape would not change because there are no unbalanced forces acting on it.

Good job with your answers! Feel free to ask any more questions if you have them.
