Force & Net Force

Front

What is force?

Back

A force is a push or pull acting upon an object as a result of its interaction with another object.

Front

What is net force?

Back

Net force is the vector sum of all the forces acting on an object.

Front

How do you determine the direction of an object's movement?

Back

The direction of an object's movement is determined by the direction of the net force acting on it.

Front

What is kinetic energy?

Back

Kinetic energy is the energy an object possesses due to its motion.

Front

What factors affect the kinetic energy of an object?

Back

Kinetic energy depends on the mass of the object and the square of its velocity (KE = 1/2 mv^2).

Front

What is the relationship between force and acceleration?

Back

According to Newton's second law, force equals mass times acceleration (F = ma).

Front

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

Back

The unit of force is the Newton (N).

Front

How do you calculate net force when multiple forces are acting on an object?

Back

To calculate net force, sum all the forces acting on the object, taking into account their directions.

Front

What happens to an object when the net force acting on it is zero?

Back

If the net force is zero, the object remains at rest or continues to move at a constant velocity.

Front

What is the significance of the point of greatest kinetic energy on a roller coaster?

Back

The point of greatest kinetic energy on a roller coaster corresponds to the lowest point in the track, where potential energy is converted to kinetic energy.
