Force and Motion Review-Physics

Front

What is the coefficient of kinetic friction?

Back

The coefficient of kinetic friction is a dimensionless value that represents the ratio of the force of kinetic friction between two bodies to the normal force pressing them together.

Front

What is the net force acting on an object?

Back

The net force is the vector sum of all the forces acting on an object. It determines the object's acceleration and direction of motion.

Front

What is inertia?

Back

Inertia is the tendency of an object to resist changes in its state of motion. It is directly related to the mass of the object.

Front

What is an action-reaction pair according to Newton's Third Law?

Back

An action-reaction pair consists of two forces that are equal in magnitude and opposite in direction, acting on two different objects.

Front

What can force do to an object?

Back

Force can accelerate an object, slow it down, keep it in place, or change its shape.

Front

What is the formula for calculating force?

Back

Force (F) is calculated using the formula F = mass (m) × acceleration (a).

Front

What is gravitational force?

Back

Gravitational force is the attractive force between two masses, proportional to the product of their masses and inversely proportional to the square of the distance between their centers.

Front

What is the difference between mass and weight?

Back

Mass is the amount of matter in an object, measured in kilograms, while weight is the force exerted by gravity on that mass, measured in newtons.

Front

What is acceleration?

Back

Acceleration is the rate of change of velocity of an object, typically measured in meters per second squared (m/s²).

Front

What is the principle of conservation of momentum?

Back

The principle of conservation of momentum states that the total momentum of a closed system remains constant if no external forces act on it.
