UNIT 4 Forces and Motion Vocab Flashcard

Front

What are forces acting upon an object that will cause the object to remain as it is?

Back

Balanced forces are equal in size and opposite in direction, resulting in no change in motion.

Front

What is a force that moves an object toward you?

Back

A pull is a force that draws an object closer.

Front

According to Newton's second law of motion, what is the equation that relates force, mass, and acceleration?

Back

The equation is F = ma, where F is force, m is mass, and a is acceleration.

Front

What is the term for movement; an object moving to a new location?

Back

Motion refers to the change in position of an object over time.

Front

What is an object speeding up or slowing down due to forces acting upon it?

Back

Acceleration is the rate of change of velocity of an object.

Front

What is the difference between speed and velocity?

Back

Speed is a scalar quantity that refers to how fast an object is moving, while velocity is a vector quantity that includes both speed and direction.

Front

What is inertia?

Back

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

Front

What is the unit of force in the International System of Units (SI)?

Back

The unit of force is the Newton (N).

Front

What is the relationship between mass and weight?

Back

Weight is the force exerted by gravity on an object, calculated as weight = mass × gravitational acceleration (W = mg).

Front

What is the effect of unbalanced forces on an object?

Back

Unbalanced forces cause an object to accelerate, changing its velocity.
