Newton's Laws of Motion - Physics 101 / AP Physics 1 Review - Dianna Cowern

Dianna Cowern introduces Newton's laws of motion, focusing on inertia, force, and acceleration. She explains Newton's first law with examples like a skater and balloons, emphasizing inertia. The second law, F=ma, is explored through examples involving cows and gravity. The third law, equal and opposite forces, is demonstrated with practical examples. The lesson concludes with a summary and a glimpse into advanced physics concepts.

What is the main theme of the lesson introduced by Dianna?

• The theory of relativity

• May the force be with you

• Quantum mechanics

• The speed of light

According to Newton's First Law, what happens to an object in motion if no external force acts on it?

• It stops immediately

• It changes direction

• It accelerates

• It continues moving at a constant velocity

What is the relationship between mass and inertia?

• Inertia is independent of mass

• More mass means more inertia

• More mass means less inertia

• Mass is unrelated to inertia

What is the formula that represents Newton's Second Law of Motion?

• V = IR

• E = mc^2

• P = mv

• F = ma

What unit is used to measure force in the International System of Units?

• Joules

• Pascals

• Watts

• Newtons

What is the force called that balances the gravitational force on a hanging object?

• Tension

• Friction

• Electrostatic

• Magnetic

If a 1 kg object is subjected to Earth's gravity, what is the approximate force acting on it?

• 10 Newtons

• 15 Newtons

• 1 Newton

• 5 Newtons

What happens to the net force on an object if it is not accelerating?

• The net force is zero

• The net force is increasing

• The net force is decreasing

• The net force is constant but non-zero

According to Newton's Third Law, what happens when you push on an object?

• The object does not move

• The object pushes back with an equal force

• The object moves in the opposite direction

• The object accelerates indefinitely

What is an example of Newton's Third Law in everyday life?

• A person walking

• A book resting on a table

• A rocket launching

• A car accelerating
