Forces

Front

What is Air Resistance or Drag?

Back

Air Resistance or Drag is a force that opposes the motion of an object through the air, slowing it down.

Front

What is Gravity?

Back

Gravity is a non-contact force that pulls objects towards each other, such as the Earth pulling objects towards its center.

Front

How does distance affect gravity?

Back

The greater the distance between two objects, the less gravity affects them.

Front

What happens to a hammer and a feather dropped on the moon?

Back

Both hit the ground at the same time because there is no air resistance on the moon.

Front

What two forces act on a dog tumbling through the air?

Back

Gravity and friction are the two forces acting on the dog.

Front

What is a contact force?

Back

A contact force is a force that requires physical contact between two objects, such as friction.

Front

What is a non-contact force?

Back

A non-contact force is a force that acts at a distance, such as gravity or magnetism.

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 the effect of gravity on falling objects?

Back

Gravity causes all objects to accelerate towards the Earth at the same rate, regardless of their mass.

Front

What is the role of air resistance in skydiving?

Back

Air resistance slows down a skydiver as they fall, allowing for a safer landing.
