Question

1. this machine makes things look bigger on the wall so everyone in the classroom can see the writing. projectile trajectory projector jettison 8. the higher the paper airplane goes, the wider the angle of which of the following? projectile trajectory projector jettison

Explanation:

• For question 7: A projector is a machine that projects an image onto a surface (like a wall) to make it visible and larger. A projectile is an object in motion (e.g., a thrown ball), trajectory is the path of an object in motion, and jettison means to discard something.
• For question 8: The trajectory is the path of an object (like a paper airplane). As the paper airplane goes higher, the angle of its trajectory (the path it follows) widens. A projectile is the object itself (the paper airplane), a projector is a machine, and jettison is to discard.

Answer:

1. projector
2. trajectory
