Newton's Laws of Motion

Which statement is true about the picture?

• A soccer ball at rest will remain at rest unless an external force causes it to move

• A soccer ball will at rest will remain stationary even if an external force is applied

• A soccer ball will remain stationary until friction will push it to move

• A soccer ball will stay at rest until another soccer ball will collided with it

What conclusion can be drawn from the experiment?

• The more force applied to the soccer ball, the farther it goes

• The lesser the force applied to the soccer ball, the farther it goes

• The more mass a soccer ball has, the more force needed to move it

• The less mass a soccer ball has, the more force needed to move it.
