Forces and Mechanical Advantage Concepts

Front

What is the difference between distance and displacement?

Back

Distance is the total path length traveled, while displacement is the shortest straight line from the starting point to the ending point.

Front

What is mechanical advantage?

Back

Mechanical advantage is the ratio of the output force produced by a machine to the input force applied to it.

Front

How do you calculate mechanical advantage for an inclined plane?

Back

Mechanical advantage = Length of the incline / Height of the incline.

Front

What is the formula for force according to Newton's second law?

Back

Force (F) = Mass (m) x Acceleration (a).

Front

If a block is pushed with a force of 15 N and accelerates at 3.0 m/s², what is the mass of the block?

Back

Mass = Force / Acceleration = 15 N / 3.0 m/s² = 5 kg.

What is the purpose of using a pulley system?

Back

A pulley system is used to lift heavy objects with less effort by changing the direction of the force applied.

Front

What is the significance of the slope of an inclined plane?

Back

The slope determines the amount of force needed to lift an object; a gentler slope requires less force.

Front

What is the relationship between force, mass, and acceleration?

Back

The relationship is directly proportional; as mass increases, more force is needed to achieve the same acceleration.

What is the unit of force in the International System of Units (SI)?

Back

The unit of force is the Newton (N).
