Forces, friction and gravity basics

Front

What type of friction acts on objects that are sliding over a surface?

Back

Sliding Friction

Front

What is the net force acting on an object if the forces are balanced and equal to 5 N to the left?

Back

5 N left

Front

What type of friction acts on objects that are not moving?

Back

Static Friction

Front

What is the term for fluid friction acting on an object moving through the air?

Back

Air Resistance

Front

What is the term for the constant velocity of a falling object when the force of air resistance equals the force of gravity?

Back

Terminal Velocity

Front

What is the force that opposes the motion of an object in contact with a surface?

Back

Friction

Front

What is the difference between static friction and kinetic friction?

Back

Static friction acts on stationary objects, while kinetic friction acts on moving objects.

Front

What happens to the net force when an object is in free fall?

Back

The net force is equal to the weight of the object, as air resistance is negligible.

Front

What is the effect of increasing the surface area of an object on air resistance?

Back

Increasing the surface area increases air resistance.

Front

What is the relationship between mass and gravitational force?

Back

Gravitational force increases with mass.
