Force and Motion Chapter 2 Flashcard

Front

What is the definition of mass in physics?

Back

Mass is the amount of matter that makes up an object.

Front

How does mass affect the velocity change of an object in a collision?

Back

If objects in a collision have different masses, their changes in velocity will be different.

Front

What role does mass play in the rate at which objects slow down due to friction?

Back

Two objects with the same initial velocity will stop or slow down at different rates based on their mass.

How does unloading rocks from a wheelbarrow affect the force needed to move it?

Back

Decreasing the mass of the wheelbarrow makes it easier to move.

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

Back

Force equals mass times acceleration (F = ma).

What is inertia and how does it relate to mass?

Back

Inertia is the resistance of an object to change its state of motion, and it is directly related to the mass of the object.

How does friction affect the motion of objects with different masses?

Back

Friction acts on all objects, but its effect on motion varies based on the mass of the objects.

What is the formula for calculating weight?

Back

Weight is calculated as mass times the acceleration due to gravity (W = mg).

Front

How does the concept of momentum relate to mass and velocity?

Back

Momentum is the product of mass and velocity (p = mv), meaning that both mass and velocity affect an object's momentum.
