Honors Forces Test Review

Front

What is Newton's Second Law of Motion?

Back

Acceleration is directly proportional to the net force acting on an object and inversely proportional to its mass. (F = ma)

Front

What is the formula to calculate acceleration?

Back

Acceleration (a) = (Final Velocity (v_f) - Initial Velocity (v_i)) / Time (t)

Front

What is static friction?

Back

Static friction is the force that keeps an object at rest and prevents it from moving when a force is applied.

Front

What is kinetic friction?

Back

Kinetic friction is the force that opposes the motion of an object that is already in motion.

Front

How does the coefficient of friction affect motion?

Back

The coefficient of friction determines the amount of frictional force between two surfaces; a higher coefficient means more friction.

Front

What is the relationship between mass and acceleration according to Newton's Second Law?

Back

As mass increases, acceleration decreases for a given force.

Front

What is the direction of acceleration when an object slows down?

Back

The direction of acceleration is opposite to the direction of motion.

Front

What is the significance of an unbalanced force?

Back

An unbalanced force causes a change in the motion of an object, according to Newton's First Law.

Front

What happens to an object at rest when a force is applied?

Back

If the applied force exceeds static friction, the object will start to move.

Front

What is the formula for calculating the net force acting on an object?

Back

Net Force (F_net) = Mass (m) x Acceleration (a) or F_net = F_applied - F_friction.
