Changes in Force and Motion

Front

What is the formula for speed?

Back

S = d/t

Front

What determines the motion of an object?

Back

The sum of the forces acting on it.

Front

What is the total amount of force on an object called?

Back

Net Force

Front

What is the formula for Newton's 2nd Law?

Back

F = ma

Front

What happens to the force needed to change an object's motion as its mass increases?

Back

The greater the mass of the object, the greater the force needed to achieve the same change in motion.

Front

What is inertia?

Back

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

Front

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

Back

According to Newton's 2nd Law, force equals mass times acceleration (F = ma).

Front

What is the difference between balanced and unbalanced forces?

Back

Balanced forces do not change an object's motion, while unbalanced forces cause an object to accelerate.

Front

What is acceleration?

Back

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

Front

What is the unit of force?

Back

The unit of force is the Newton (N).
