Displacement, Velocity, Acceleration, Force
A horse exerts 800 N of force on a heavy wagon, causing it to accelerate. Determine the force the wagon exerts on the horse
What is 800 N?
Write the correct equation for velocity
What is:
Velocity = (Final Position - Inital Position) / Total Time
A man leaves his coffee on his car while he unlocks it. He forgets about it and begins driving away. Explain why his coffee slides off the car as he begins to drive
The coffee did not feel a force, and so its inertia wanted it to stay where it was
