Front

What is net force?

Back

Net force is the vector sum of all the forces acting on an object, representing both the size and direction of those forces.

Front

What does chronic injury mean?

Back

Chronic injury refers to injuries that develop gradually over time, often due to repeated stress or overuse.

Front

True or False: Weight is the quantity of matter contained in an object.

Back

False. Weight is the force exerted by gravity on an object, while mass is the quantity of matter.

Front

What is the difference between mass and weight?

Back

Mass is the amount of matter in an object, measured in kilograms, while weight is the force of gravity acting on that mass, measured in newtons.

Front

Define force in physics.

Back

A force is a push or pull acting upon an object, resulting from its interaction with another object.

Front

What is the formula for calculating net force?

Back

Net force (F_net) = F_applied + F_friction + F_gravity + ... (sum of all forces acting on the object).

Front

What is the significance of direction in net force?

Back

The direction of net force determines the direction of an object's acceleration according to Newton's second law of motion.

Front

What are stress injuries?

Back

Stress injuries are injuries that occur due to repetitive trauma or overuse, often affecting muscles, tendons, and bones.

Front

What is the role of gravity in determining weight?

Back

Gravity pulls objects towards the center of the Earth, and weight is the measure of this gravitational force on an object's mass.

Front

What is an example of a chronic injury?

Back

An example of a chronic injury is tendonitis, which results from repetitive motion and overuse of a tendon.
