Types of Forces
What type of force acts within a structure and can change its shape or size?
Internal Force
What type of structure is designed to hold weight and resist forces?
supporting structure
What adaptation helps a turtle protect itself from predators and environmental forces?
hard shell
What type of weather force can push against a building and create tension or compression?
wind
What protective equipment helps reduce the impact of a hit to the head in sports?
helmet
Which force is created when a rope is pulled?
Tension
What type of structure stretches across space and provides support, like a bridge?
spanning structure
What structural adaptation helps an Arctic fox survive in cold environments?
thick fur
What weather condition adds weight to roofs, creating compression forces?
What force is absorbed by knee pads during a fall in sports?
compression
What type of forces act in equal sizes but opposite directions, causing no movement?
balanced forces
What type of structure surrounds and protects an area, such as a dome or greenhouse?
enclosing structure
What is the adaption of a cactus that helps it survive in the desert?
Thick, waxy skin and spines
Prevents water loss and protects from extreme desert heat.
In areas with frequent earthquakes, what engineering techniques are used to ensure buildings can resist seismic forces?
strong foundations and shock absorbers, flexible materials
In football, what type of force is acting on the body when a player tackles another player?
compression
What happens to a soccer ball when the forces acting on it are unbalanced?
It moves or changes direction
What is the force that acts on a building from wind, causing tension or compression?
external force
What is the structural adaptation of the baobab tree?
Thick trunk and large leaves
Stores water in the trunk to survive droughts in arid climates.
Flooding caused by heavy rain effects buildings, engineering solutions are used to protect structures?
flood barriers or use waterproof materials
In gymnastics, when an athlete twists their body in mid-air, which internal force is involved in the movement?
torsion
Which type of force acts on an object from a distance?
a non-contact force
What type of structure uses pillars or columns to support weight?
supporting structure
what are the structural adaptations of the Redwood Tree?
Thick bark
Protects from wildfires and extreme temperatures.
When heavy snow or ice accumulates on a roof it creates compression. How can engineers help? Engineers may reinforce roofs with stronger materials or design them with a sloped shape to allow snow to slide off.
Engineers may reinforce roofs with stronger materials or design them with a sloped shape to allow snow to slide off. Heated roofs.
How does a helmet reduce the risk of brain injury in contact sports like football?
by absorbing and spreading out the force from hits, preventing the skull from taking the full impact
