Unit 3 Forces Vocabulary

Front

What is the overall force acting on an object after all individual forces are combined?

Back

Net force

Front

What is the term for the path of an object thrown through the air due to the horizontal force of velocity and the vertical force of gravity?

Back

Projectile motion

Front

What is the SI unit for force, defined as the force that causes a 1-kg mass to accelerate at a rate of 1 m/s²?

Back

Newton

Front

What is the term for the fluid friction acting on an object moving through the air?

Back

Air resistance

Front

What does Newton's 1st Law state about the motion of an object at rest and an object in motion?

Back

An object at rest will remain at rest unless acted on by an unbalanced force. An object in motion continues in motion with the same speed and in the same direction unless acted upon by an unbalanced force.

Front

What is the relationship between mass and acceleration in Newton's second law of motion?

Back

Force equals mass times acceleration (F = ma).

Front

What is the term for the force that opposes the motion of an object through a fluid?

Back

Drag force.

Front

What is the effect of balanced forces on an object's motion?

Back

Balanced forces do not change the motion of an object.

Front

What is inertia in the context of Newton's laws?

Back

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

Front

What is the difference between mass and weight?

Back

Mass is the amount of matter in an object, while weight is the force of gravity acting on that mass.
