Weight, Friction, and Equlibrium

Front

What is the product of friction?

Back

Front

Back

Rolling friction

Front

Back

Air friction

Front

If a 25 kg object accelerates at 5 m/s², what is the force?

Back

125 N

Front

Which law states that for every action, there is an equal and opposite reaction?

Back

3rd Law (action-reaction)

Front

What is weight?

Back

The force exerted by gravity on an object, calculated as mass times gravitational acceleration (W = mg).

Front

What is equilibrium?

Back

A state where the sum of forces acting on an object is zero, resulting in no acceleration.

Front

What is the formula for calculating force?

Back

F = ma (Force = mass × acceleration)

Front

What is sliding friction?

Back

The resistance encountered when two surfaces slide against each other.

Front

What is viscous friction?

Back

The resistance encountered when an object moves through a fluid.
