Force and Friction

Front

What is the standard unit of force?

Back

Newton (N)

Front

What is the tendency of an object to stay in motion or at rest called?

Back

Inertia

Front

What type of force occurs when two forces are not equal and cause a change in motion?

Back

Unbalanced Force

Front

How do you calculate the net force when two forces are acting in the same direction?

Back

Add the magnitudes of the forces.

Front

What do balanced forces do to an object's speed and direction?

Back

They do not change the object's speed or direction.

Front

What is the force that opposes the motion of an object?

Back

Friction

Front

What is the relationship between mass and inertia?

Back

The greater the mass of an object, the greater its inertia.

Front

What is the formula for calculating force?

Back

Force = mass × acceleration (F = ma)

Front

What is static friction?

Back

The frictional force that prevents two surfaces from sliding past each other.

Front

What is kinetic friction?

Back

The frictional force acting between moving surfaces.
