Dynamics B

Front

What is net force?

Back

The sum of all forces acting on a body, determining its acceleration.

Front

How do you calculate net force when multiple forces are acting in opposite directions?

Back

Subtract the smaller force from the larger force.

Front

What is the formula for calculating force?

Back

Force (F) = mass (m) × acceleration (a).

Front

What is the weight of an object?

Back

The force exerted by gravity on an object, calculated as weight = mass × gravitational acceleration (9.8 m/s² on Earth).

Front

If an object has a mass of 500 g, what is its weight in newtons?

Back

5 N (since 500 g = 0.5 kg and weight = 0.5 kg × 9.8 m/s²).

Front

What does a free body diagram represent?

Back

A graphical illustration showing all the forces acting on an object.

Front

What is friction?

Back

A force that opposes the motion of an object, acting parallel to the surfaces in contact.

Front

How does mass affect the force required to accelerate an object?

Back

Greater mass requires more force to achieve the same acceleration (F = ma).

Front

What is the relationship between mass and weight?

Back

Weight is the gravitational force acting on a mass; weight = mass × gravitational acceleration.

Front

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

Back

Newton (N).
