Forces Unit Review

Front

What force slows objects down and keeps them from moving?

Back

Friction is the force that opposes the motion of an object, slowing it down.

Front

What is a friction force acting on a NON-moving object?

Back

Static friction is the force that keeps an object at rest and prevents it from moving.

Front

Is friction a type of force?

Back

True, friction is indeed a type of force.

Front

What unit do we measure force in?

Back

Force is measured in Newtons.

Front

What is the effect of a rightward force applied to a dresser?

Back

A rightward force applied to a dresser will accelerate it to the right across the floor.

Front

What is the difference between static friction and kinetic friction?

Back

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

Front

What is the formula for calculating force?

Back

Force (F) is calculated using the formula F = mass (m) × acceleration (a).

Front

What is gravitational force?

Back

Gravitational force is the attraction between two masses, such as the Earth and an object.

Front

What is the role of friction in everyday life?

Back

Friction allows us to walk without slipping and helps vehicles to stop.

Front

What happens to friction when the surface is smooth?

Back

Friction decreases when the surface is smooth, making it easier for objects to slide.
