Imagine Sophia, Evelyn, and Nora are having a race with their toy carts along a track. What happens to the energy of Sophia's cart as it zooms past point B on the track?
Potential energy is transformed to kinetic energy.
Kinetic energy is transformed to potential energy.
Both potential energy and kinetic energy stay the same.
Potential energy decreases and kinetic energy stays the same.
Imagine William, Noah, and Zoe are playing with a toy car. What would you call the force they exert on the toy car?
a pull exerted on an object
a measure of how heavy an object is
a push, pull or twist exerted on an object
a change in the direction of motion of an object
Rohan, Ava, and Aria are planning a science experiment to demonstrate Newton’s third law during the collision of two objects. They are debating on what kind of objects they should use to best illustrate their point. Can you help them decide?
They should use objects with the same mass, making the result of equal forces easier to see.
They should use a larger object and a smaller object. The larger object would exert more force on the smaller object, showing unequal forces instead of equal ones.
They should use objects that are the same diameter, showing equal forces during a collision, proving Newton's 3rd law.
Imagine Samuel, Aria, and Arjun are racing their remote-controlled cars. The speed of these cars determines how much kinetic energy they have. Can you describe the relationship between the speed and kinetic energy of their cars?
There is no relationship between speed and kinetic energy.
There is a linear relationship between speed and kinetic energy.
There is a constant relationship between speed and kinetic energy.
There is a nonlinear relationship between speed and kinetic energy.
Imagine Kai and Benjamin are playing catch. What kind of force allows the ball to drop if they don't catch it? (Gravity)
Contact Force
Non Contact Force
Rohan, Aiden, and Charlotte are having a debate. Rohan says that the frictional force is a contact force, while Aiden believes it's a non-contact force. Who do you think is correct?
Rohan
Aiden
Aiden, Aria, and Arjun are having a debate. Aiden thinks that air resistance force is a contact force, while Aria believes it's a non-contact force. Who do you think is correct?
Aiden
Aria
Ava and Aiden are having a debate. Ava says magnetic force is a contact force, while Aiden believes it's a non-contact force. Abigail, who do you think is correct?
Ava
Aiden
Evelyn and Liam are playing a game of tug-of-war. What kind of force is Evelyn applying on the rope? (Applied Force)
Contact
Non Contact
Imagine Daniel and Ava are having a fun playtime with their toys. Suddenly, David comes up with a challenge. He wants to move all the toys to the shelves. But, he needs to calculate the amount of work required to lift each toy. Which data do you think David would need to collect?
the length of each shelf
the time it took for David to move each toy
the amount of force David needed to lift each toy
the strength of David who moved the toy
Imagine Avery, Olivia, and Daniel are playing a game of ice hockey. If Avery slides the puck across the ice, what forces are acting on the puck?
Unbalanced forces only
Frictional force, gravitational force, magnetic force
Gravitational force and normal force.
The puck does not have any forces acting upon it
Imagine this: Olivia, Evelyn, and Aria are watching a thrilling hockey match. Suddenly, the puck slides across the ice. If you were to analyze this situation, what forces do you think are acting on the puck?
Unbalanced forces only
Frictional force, gravitational force, magnetic force
The puck does not have any forces acting upon it.
Gravitational force, applied force and normal force.
Zoe, Abigail, and Aiden are having a blast skiing downhill during their winter vacation! Can you help them figure out what forces are acting on them as they zoom down the ski slope?
Gravitational and applied force, and normal force
Gravitational force, spring force and magnetic force
Gravitational force, frictional force, and air resistance
In a tug of war game, two teams are pulling the rope in opposite directions. The rope does not move even though both teams are pulling with all their strength.
Why doesn't the rope move?
The first team is pulling in one direction. The second team is pulling in the opposite direction with an equal force. The net force is 0 N, so the forces are balanced.
The first team is pulling in one direction. The second team is pulling in the same direction with an equal force. There is an unbalanced net force so the rope does not move
The first team is pushing in one direction. The second team is pulling in the same direction with an equal force. There is an unbalanced net force so the rope does not move
The first team is pulling in one direction. The second team is pushing in the opposite direction with an equal force. The net force is 0 N, so the forces are balanced.
Which spring constant would convert into the least kinetic energy?
1,800 N/m
1,200 N/m
750 N/m
