Newton's Laws, Projectile Motion & Energy

Front

What is Newton's First Law of Motion?

Back

An object at rest stays at rest, and an object in motion stays in motion with the same speed and in the same direction unless acted upon by an unbalanced force.

Front

Define mass in physics.

Back

Mass is a measure of the amount of matter in an object, typically measured in kilograms (kg).

Front

What is inertia?

Back

Inertia is the tendency of an object to resist changes in its state of motion. The greater the mass, the greater the inertia.

Front

What is Newton's Second Law of Motion?

Back

The acceleration of an object is directly proportional to the net force acting on it and inversely proportional to its mass (F = ma).

Front

What is the formula for calculating acceleration?

Back

Acceleration (a) = Net Force (F) / Mass (m).

Front

What is the definition of fluid friction?

Back

Fluid friction is the resistance encountered by an object moving through a fluid (liquid or gas).

Front

What is the ideal launch angle for maximum range in projectile motion?

Back

The ideal launch angle for maximum range is 45 degrees.

Front

What is kinetic energy?

Back

Kinetic energy is the energy of an object due to its motion, calculated as KE = 1/2 mv², where m is mass and v is velocity.

Front

What is potential energy?

Back

Potential energy is the stored energy of an object due to its position or state, commonly gravitational potential energy, calculated as PE = mgh, where m is mass, g is acceleration due to gravity, and h is height.

Front

What is the relationship between force, mass, and acceleration?

Back

According to Newton's Second Law, the relationship is expressed as F = ma, meaning force equals mass times acceleration.
