Newton's Laws Conceptual Edit

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 a net external force.

Front

Define mass in terms of weight and gravitational acceleration.

Back

Mass is defined as weight divided by the acceleration due to gravity (m = W/g).

Front

What is the formula for calculating weight?

Back

Weight (W) is calculated using the formula W = m * g, where m is mass and g is the acceleration due to gravity.

Front

What does Newton's Second Law of Motion state?

Back

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

Front

How do you calculate the tension in a rope supporting a weight at an angle?

Back

Tension can be calculated using the formula T = W / (2 * cos(θ)), where W is the weight and θ is the angle with the horizontal.

Front

What is the significance of the coefficient of friction?

Back

The coefficient of friction is a measure of how much frictional force exists between two surfaces in contact.

Front

Explain the concept of equilibrium in physics.

Back

An object is in equilibrium when the net force acting on it is zero, meaning all forces are balanced.

Front

What is the difference between static and kinetic friction?

Back

Static friction acts on objects that are not moving, while kinetic friction acts on objects that are sliding over each other.

Front

Define inertia.

Back

Inertia is the tendency of an object to resist changes in its state of motion.

Front

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

Back

According to Newton's Second Law, force is the product of mass and acceleration (F = m * a).
