Front

What is Newton's Second Law of Motion?

Back

Newton's Second Law states that the acceleration of an object is directly proportional to the net force acting on it and inversely proportional to its mass. It can be expressed with the formula F = ma, where F is the force, m is the mass, and a is the acceleration.

Front

What is the relationship between mass and acceleration when a constant force is applied?

Back

When a constant force is applied, an object with greater mass will experience less acceleration compared to an object with less mass.

Front

How does the motion of an object change when it is acted upon by an unbalanced force?

Back

An unbalanced force causes an object to accelerate in the direction of the net force, changing its velocity.

Front

What is a free-body diagram?

Back

A free-body diagram is a graphical representation used to visualize the forces acting on an object. It shows all the external forces acting on the object and their directions.

Front

How do you calculate the final velocity of an object with constant acceleration?

Back

The final velocity can be calculated using the formula: v_f = v_i + at, where v_f is the final velocity, v_i is the initial velocity, a is the acceleration, and t is the time.

Front

What is the formula for calculating acceleration?

Back

Acceleration (a) is calculated using the formula: a = (v_f - v_i) / t, where v_f is the final velocity, v_i is the initial velocity, and t is the time taken.

Front

What does it mean for an object to be in uniform motion?

Back

An object is in uniform motion when it moves at a constant speed in a straight line, meaning its velocity does not change over time.

Front

What is the significance of the slope of a velocity-time graph?

Back

The slope of a velocity-time graph represents the acceleration of the object. A steeper slope indicates greater acceleration.

Front

How do you determine the net force acting on an object?

Back

The net force is determined by vectorially adding all the individual forces acting on the object, taking into account their directions.

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.
