Forces And Motion

Front

What is friction?

Back

Friction is a force that opposes the motion of an object when it comes into contact with another surface.

Front

What is gravity?

Back

Gravity is the force that attracts two bodies towards each other, commonly experienced as the force that pulls objects towards the Earth.

Front

What are airbags?

Back

Airbags are safety devices in vehicles that inflate upon impact to cushion passengers and reduce injury during a collision.

Front

What are seatbelts?

Back

Seatbelts are safety harnesses in vehicles designed to secure passengers and prevent them from being thrown forward during a sudden stop or crash.

Front

What are crumple zones?

Back

Crumple zones are areas of a vehicle designed to deform and absorb energy during a collision, increasing the time of impact and reducing injury.

Front

What is the role of turn signals in a car?

Back

Turn signals are indicators used to communicate a driver's intention to turn or change lanes, but they do not contribute to safety during a collision.

Front

What is the effect of increasing friction on a vehicle in snow?

Back

Increasing friction helps improve traction, allowing the vehicle to grip the road better and avoid slipping.

Front

What is the relationship between mass and gravitational force?

Back

The greater the mass of an object, the stronger the gravitational force it exerts on other objects.

Front

What is the difference between static and kinetic friction?

Back

Static friction acts on objects that are not moving, while kinetic friction acts on objects that are sliding over each other.

Front

What is inertia?

Back

Inertia is the tendency of an object to resist changes in its state of motion; an object at rest stays at rest, and an object in motion stays in motion.
