Phys Sci 9 Forces

You are standing still holding a plate of wings, when Notre Dame beats a Top 10 team! What?!? As you start to go into shock you stumble and the wings fall to the floor. You realize

• This could not happen in real life

• Wings spilled due to friction and air resistance

• College football can be stressful

• The wings wanted to stay on the plate, but you moved

You're on a boat with yr significant other & best friend. Both fall into the water and need help. You jump into the water to save one of them and the boat changes position why?

• Since your BF has all your science warm-ups you save the BF

• Your significant other has a list of all of Mr. Goss' puns from this year! You know who to save!

• For every action there is an equal but opposite reaction

• Objects at rest always stay at rest

Timmy goes for a walk after passing their Science Test. This graph represents distance from school. Descibe this walk

• Not sure, I ride the bus to school

• They walked away from the school, rested, then walked further away from school

• They walked at a constant rate, not stopping until the end

• They walk in a direction, rested for a bit, then walked in the opposite direction

On the International Space Station, astronauts appear weightless bc

• Astronauts have gravitational attractions to each other (just friends, though)

• Astronauts have no mass in space

• There is no gravity in outer space

• The astronauts are in a state of free fall

We want to accelerate a 60 kg unicorn on a 50 kg scooter (yeah that happens) 3 m/s². How much force is needed?

• 3,000 Newtons

• 300 Newtons

• 330 Newtons

• 3,330

After the game, an upset fan throws their cell phone against a wall. What happens?

• The cell phone exerts a force on the wall and the wall exerts a force back

• The cell phone will slice through the wall like heated queso

• The cell phone bounces off the wall and is always unharmed

• The cell phone does not have enough mass to exert force on the wall

Timmy popped the head off his sister's Barbie doll and rolls it down an incline. He collects data on the rolling head. What graph will best show instantaneous acceleration from the slope of the graph?

• Velocity on the y axis, distance on the x axis

• Velocity on x-axis, distance on y axis

• Distance on y-axis, time on x-axis

• Velocity on y-axis, time on x-axis

A Jedi and Sith went for a hike. On Day 1 they were 5 km away from the cabin. On Day 2 they were 15 km away from the cabin. On Day 3 they headed back to the cabin, but stopped when they were 5 km away form the cabin. On Day 3, what is their displacement?

• 20 km

• 15 km

• 25 km

• 5 km

Based on the red and green lines on the graph, describe the acceleration of these two objects:

• Red has no acceleration, green has negative

• Red has no acceleration, green speeds up and slows down

• Red has positive acceleration, green has negative

• Red has constant acceleration, green has varied
