Newton's Laws of Motion

Front

What is the definition of an unbalanced force?

Back

An unbalanced force is a force that causes an object to change its state of motion, resulting in acceleration.

Front

State Newton's 2nd law of motion.

Back

Newton's 2nd law of motion states that Force equals Mass multiplied by Acceleration (F = ma).

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.

Front

What does Newton's 1st law of motion state?

Back

Newton's 1st law of motion states that an object at rest will remain at rest, and an object in motion will remain in motion at a constant velocity unless acted upon by an unbalanced force.

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 acceleration according to Newton's 2nd law?

Back

According to Newton's 2nd law, an increase in mass will result in a decrease in acceleration if the force applied remains constant.

Front

What is the formula for calculating force?

Back

The formula for calculating force is F = ma, where F is force, m is mass, and a is acceleration.

Front

What is the significance of a free-body diagram?

Back

A free-body diagram is used to visualize the forces acting on an object, helping to analyze the net force and resulting motion.

Front

What happens to an object's motion when balanced forces act on it?

Back

When balanced forces act on an object, there is no change in its motion; it either remains at rest or continues to move at a constant velocity.

Front

What is the relationship between acceleration and net force?

Back

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