Physics 3 2.6

Front

What is the effect of friction on the motion of an object?

Back

Friction opposes the motion of an object, causing it to slow down or stop.

Front

How does an unbalanced force affect the motion of an object?

Back

An unbalanced force causes an object to accelerate, changing its speed or direction.

What is a balanced force?

Back

A balanced force occurs when two forces acting on an object are equal in size and opposite in direction, resulting in no change in motion.

Front

What is tension force?

Back

Tension force is the force transmitted through a string, rope, or cable when it is pulled tight by forces acting from opposite ends.

Front

What happens to an object in motion when no net force acts on it?

Back

The object will continue to move at a constant speed in a straight line.

Front

What is inertia?

Back

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

Front

How does mass affect inertia?

Back

The greater the mass of an object, the greater its inertia, making it harder to change its motion.

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 at a constant velocity unless acted upon by a net external force.

Front

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

Back

According to Newton's second law, force equals mass times acceleration (F = ma).

What is an example of a situation with balanced forces?

Back

A book resting on a table experiences balanced forces: the gravitational force downward and the normal force upward are equal.
