- Q1Which of the following is true of field forces?Field forces DO NOT exist.A force that REQUIRES contact.Magnets are the ONLY object known to have field forces.A force that can be exerted WITHOUT contact.60sMS-PS2-5
- Q2Electric field lines show that the force between an electron (negative charge) and a proton (positive charge)has no effect on the particles.causes the particles to move toward each other.makes the particles vibrate in place.causes the particles to move away from each other.60sMS-PS2-3
- Q3As the distance between two positively charged objects increases, the force between them:cannot be determined.remains the same.increases.decreases.60sMS-PS2-3
- Q4When we used the Van De Graff generator, Why did the rabbit hair and student hair rise away from their body?The hair is charged negative and they repel each other.Like cats when you are scared the hairs stand up.The positive charges in the hair move to the end causing the hair to move.The hair is attracted to the positively charged ceiling.60sMS-PS2-3
- Q5What happens to the gravitational force when we move two objects closer together?The force stays the same.What happens to the gravitational force when we move two objects closer together?Distance is not a factor for gravity.The force increases.60sMS-PS2-3
