Projectile Motion Answers

Which arrow indicates the direction of centripetal force on the object represented by the dot?

How are uniform circular motion maps the same as linear motion maps? Check all that apply.Time is represented by dots at 1-second intervals.Start position is represented by an x.Velocity vectors change length as the object’s speed changes.Velocity vectors change direction as the object’s direction changes.Acceleration vectors always point in the same direction.

Which statements about inertia and centripetal force are correct? Check all that apply.Inertia is always present.Inertia causes objects to continue moving in circles.Centripetal force is always present.Centripetal force pulls objects toward the center of a circle.Inertia and centripetal force cause circular motion.
