Physics 1 H Final Exam

Front

What is the effect of a parachute on a skydiver's impact force during landing?

Back

It reduces the impact force by increasing air resistance.

Front

What is the net force on an object if multiple forces are acting on it?

Back

The net force is the vector sum of all individual forces acting on the object.

Front

How do mass and weight differ?

Back

Mass is constant, while weight varies with gravitational force.

Front

What type of circuit allows other components to function if one fails?

Back

B-Parallel circuit.

Front

Which of Newton's laws states that an object at rest stays at rest unless acted upon by a net external force?

Back

Newton's 1st law.

Front

What is the formula for calculating weight?

Back

Weight = mass × gravitational acceleration (W = mg).

Front

Define air resistance and its effect on falling objects.

Back

Air resistance is a force that opposes the motion of an object through air, reducing its acceleration and impact force.

Front

What is the principle of conservation of momentum?

Back

In a closed system, the total momentum before an event is equal to the total momentum after the event.

Front

Explain the concept of net force.

Back

Net force is the overall force acting on an object when all individual forces are combined.

Front

What is the relationship between force, mass, and acceleration according to Newton's 2nd law?

Back

Force = mass × acceleration (F = ma).
