12 Questions
What happens when Katie starts paddling in terms of the forces acting on the kayak?
The applied force in the forwards direction is greater than the friction force, resulting in unbalanced forces and acceleration.
Explain the forces acting on the kayak when Katie is paddling at a constant speed.
The applied force is equal to the drag force, leading to balanced forces and no acceleration.
What occurs when Katie stops paddling with regards to the forces on the kayak?
The applied force ceases, leaving only the drag force, resulting in unbalanced forces and deceleration.
How does the relationship between applied force and friction affect the motion of the kayak?
When the applied force is greater than the friction force, the kayak accelerates.
Why is there no vertical motion in the context of weight and buoyancy when Katie is paddling?
Weight and buoyancy are balanced, resulting in no vertical motion.
In a scenario where the kayak is moving at a constant speed, what can be said about the net force acting on the kayak?
At constant speed, the net force on the kayak is zero as the applied force equals the drag force.
What is the result of the applied force being greater than the friction force while Katie is paddling?
The kayak accelerates (speeds up)
When Katie is paddling at a constant speed, what can be said about the net force acting on the kayak?
The net force is zero (Fnet = 0)
What happens when Katie stops paddling in terms of the forces acting on the kayak?
The kayak decelerates (slows down)
How does the kayak's motion change when the applied force is less than the friction force?
The kayak slows down (decelerates)
Explain the effect on the kayak when the applied force is equal to the friction force while paddling.
The kayak moves at a constant speed
What is the outcome of weight and buoyancy being balanced in the context of vertical motion while Katie paddles?
There is no vertical motion
Understand how forces like applied force and water resistance affect the motion of a kayak. Learn about how unbalanced forces lead to acceleration in the direction of motion.
