JaNoah and Jayden are competing in a science fair challenge. Their task is to design a small car that can move without being touched. JaNoah uses a magnet under the car and another in his hand to push the car forward. Jayden sets up a ramp and lets gravity pull his car down. They observe and measure how the cars move, discussing how contact and non-contact forces influence the motion of their cars.

Match the force with its correct description:

• Friction

• A contact force that resists motion between surfaces.

• Non-contact force

• A non-contact force caused by magnets.

• Magnetic force

• A force that requires two objects to touch, like pushing or pulling.

• Contact force

• A force that acts at a distance, like gravity or magnetism.

Reorder the steps to describe how JaNoah’s magnet moves the car:

• JaNoah holds a magnet near the car.

• The magnetic force repels the magnet on the car.

• The car begins to move away from JaNoah’s magnet.

• The distance between the car and JaNoah’s magnet changes the force strength.

The Mars rover Curiosity launched from Florida in 2011. About eighteen months later, it landed on the surface of Mars. Though not the first rover to be on Mars, it is the largest with a mass of about 899 kilograms. Weight changes from one place to another in space due to gravitational force as shown using an example bowling ball in the image below. On Earth, Curiosity weighs 1,982 pounds. The data in the table was collected to show what Curiosity would weigh on different terrestrial objects in our inner solar system. The evidence in the image supports which argument?

• Mars and Curiosity do not exert gravitational forces on one another.

• Mars exerts the greatest gravitational force of all three celestial objects.

• The moon and Curiosity have the least gravitational force between them.

• Earth exerts about the same gravitational force on Curiosity as Mars does.
