Engineering a Solution to a Collision Problem
The bird flies over different surfaces . how will the srface onto which the bird drops the clam affect whether the clam will open ?
Hard, Rigid Surfaces (e.g., Rocks, Pavement):
When a clam is dropped onto a hard surface, the impact force is often sufficient to cause the shell to crack or break open. The sudden jolt can rupture the shell, exposing the soft interior and causing the clam to open or even shatter.
How can Newton's Laws of motion be used to analyze the collision between two objects?
What percent of Earth is covered by water and ice?
Approximately 71% of Earth's surface is covered by water and ice.
When an object moves, it has kinetic energy. If it collides with another object and some of that energy is converted into heat (due to friction or deformation), the heat can often be detected through temperature changes or infrared imaging.
What force are acting on the golf tee when it is at rest on the hoop ?
gravity,force,friction.
Based on the description of a crash test engineer's job ,which of these engineering tasks would the engineer work on ?
In a simple collision between two objects , newton's laws of motion can be used to describe the motion of which of the objects ?
Newton's Laws apply to all objects:
Each object experiences forces during the collision, and their motions are governed by these forces according to Newton's Laws
What percent of Earth's water is fresh water?
About 2.5% of Earth's total water is freshwater.
What kind of energy is kinetic energy?
Kinetic energy is the energy of motion,
What forces are acting on the golf tee when it is falling in the bottle?
Gravity Air vesistonce
Which of the following may affect a passenger's safety during a collision ?
What happens according to Newton if you let an untied balloon go?
What do you mean by water conservation ?
What kind of energy is potential energy?
stored energy
The meaning of the word movement?
the action or process of moving or of changing place or position;
automobils did not always have safety devices such as safety belts, airbags ,and roll cages .what societal needs led to the creation of these safety measures and the career of crash test engineering ?
Reducing Injury and Fatalities:
As automobile use increased, so did the number of traffic accidents resulting in injuries and deaths. Society recognized the need to protect vehicle occupants from harm during collisions.
Why should we wear seatbelts – use one of Newton’s Laws in your answer?
We cannot drink water from sea/ocean because it is?
We cannot drink water from the sea or ocean because it is salty—specifically, it contains high concentrations of dissolved salts, primarily sodium chloride (common salt), along with other minerals.
What kind of energy is Gravitational Potential Energy?
Energy associated with the movement of objects (e.g., a car moving)
The meaning of the word speed
rapidity in moving, going, traveling, proceeding, or performing; swiftness; celerity
The blue team is rolling one of their balls toward another of their balls ,which is touching an opponent's ball as shown . What do you predict will happen when the balls collide ?
Using Newton’s laws explain why heavier objects require more force than lighter objects to move or accelerate them?
Newton's Second Law states:
The force needed to accelerate an object is directly proportional to its mass (mmm) and the acceleration (aaa) you want to give it.
What is the percentage of salinity in water?
35%
What kind of energy is electrical energy?
Energy associated with the flow of electric charges (e.g., lightning).
The meaning of the word velocity
quickness of motion
