*Rocketry and Forces Review

What is force as defined in the context of forces and motion in rocketry?

• The property of matter that causes objects to resist any change in its motion

• A push or a pull exerted on an object

• The parts that keep a rocket flying straight

• The attractive force between objects

Which of the following best describes gravity?

• A force that works against forward motion

• The parts that keep a rocket flying straight

• A heavy substance used to add stability or weight

What is inertia?

• The force that works against forward motion

• The energy to move a vehicle, such as a rocket engine

• The property of matter that causes objects to resist any change in its motion in either direction or speed

• A measure of the gravitational force exerted on an object
