IPC Unit 6 Lesson 6

What is the weight of an object on the Earth's surface that has a mass of 95 kg?

931 N

As distance increases, gravitational force ____.

Decreases

As mass decreases, gravitational force ____.

Decreases

Choose True or False. If False, choose the statement that makes it True. On Earth, the force of gravity causes all objects to fall with an acceleration of 8.9 m/s².

False. On Earth, the force of gravity causes all objects to fall with an acceleration of 9.8 m/s².

Choose True or False. If False, choose the statement that makes it True. If a ball and feather are released from a height of 10 meters at the same time, and there is no air friction or other forces, the ball would reach the ground before the feather.

False; If a ball and feather are released from a height of 10 meters at the same time, and there is no air friction or other forces, the ball and feather would reach the ground at the same time.

an attractive force between any two objects with mass

Gravity

Choose True or False. If False, choose the statement that makes it True. Gravity exists between a pencil and a coffee mug.

True

Choose True or False. If False, choose the statement that makes it True. The moon is a satellite of Earth

True

an object that orbits around the Earth

Satellite

the gravitational force exerted on the mass of an object

Weight

What would the weight of this object be if it were traveling on the planet Mercury? Mercury has an acceleration of gravity equal to 3.7 m/s2.

351.5 N

What makes projectile motion possible?

Horizontal motion plus gravity causes the curved shape of projectile motion.

the motion of an object that curves down toward the ground due to the combination of horizontal forces and the downward force of gravity
