"Hung Up"

“Hung Up”

Contrived

The physics concept being demonstrated is mainly the force of tension on an object. As the object is hanging from the clothesline gravity is acting on it pulling it down at a rate of -9.8. However, the reason the object does not full is because the force of tension is acting on it. The string holding it up is connected to the clothes hanger that I am holding. Also take note of the slight bend in the clothes hanger due to the force to object and gravity is exerting towards the ground.

“The Arcing Ball”

The picture is demonstrating the velocity and acceleration of the ball going through the air. As I through the ball it starts with a initial acceleration and is being pulled down by gravity at a constant rate throughout time it Is in the air. Its velocity stays around the same until it hits the ground and stops. The pattern of motion of the ball will end up looking like a parabolic curve with a peak when it’s velocity is zero and the ball stops.

“Almost Run Away Calculator”

“Almost Run Away Calculator”

The physics concept being demonstrated here is static friction. Static friction is friction between two or more solid objects that are not moving relative to each other. The static friction between the calculator and the place mat is high enough that the calculator does not move at this angle. Once it does start to move it transitions into kinetic friction between two moving objects. This would occur if the angle increased just past what the picture is demonstrating. Finally, the rubber on the back of the calculator also plays a role in the calculator’s resistance to move.
