Forces and motion

Front

What is Newton's 2nd law?

Back

f = ma (Force equals mass times acceleration)

Front

How does the mass of an object affect the motion of an object?

Back

The greater the mass, the less effect a force will have.

Front

What formula is used to find Force?

Back

Force = mass x acceleration (F = m x a)

Front

What formula is used to find Speed?

Back

Speed = Distance / Time (S = D/T)

Front

What does a flat line on a distance-time graph represent?

Back

Not moving.

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 and acceleration?

Back

Acceleration is directly proportional to the net force acting on an object and inversely proportional to its mass.

Front

What is the formula for calculating acceleration?

Back

Acceleration = (Final Velocity - Initial Velocity) / Time

Front

What is the unit of force?

Back

Newton (N)

Front

What is the difference between speed and velocity?

Back

Speed is a scalar quantity (magnitude only), while velocity is a vector quantity (magnitude and direction).
