Front

What does the term 'net force' refer to?

Back

Front

What happens to an object if its weight is greater than the buoyant force?

Back

The object will sink.

Front

What does density depend on?

Back

Density depends on how tightly the atoms are packed in a material.

Front

What are the three components of Newton's second law of motion?

Back

Force, mass, and acceleration.

Front

Define buoyant force.

Back

Buoyant force is the upward force exerted by a fluid on an object immersed in it.

Front

What is the formula for calculating density?

Back

Density = Mass / Volume.

Front

What is the relationship between mass and weight?

Back

Weight is the force exerted by gravity on an object's mass.

Front

What is acceleration?

Back

Acceleration is the rate of change of velocity of an object.

Front

What is the principle of conservation of energy?

Back

The principle states that energy cannot be created or destroyed, only transformed from one form to another.
