Force-Laws of Motion

Front

What is the net force?

Back

The net force is the overall force acting on an object when all the individual forces are combined. It determines the object's acceleration and direction of motion.

Front

What does it mean when an object is stationary?

Back

An object is stationary when it is not moving and its velocity is zero.

Front

What is acceleration?

Back

Acceleration is the rate of change of velocity of an object. It can be caused by a change in speed or direction.

Front

What is friction?

Back

Friction is a force that opposes the motion of an object. It occurs when two surfaces rub against each other.

Front

What is inertia?

Back

Inertia is the tendency of an object to resist changes in its state of motion. All objects with mass have inertia.

Front

What is the relationship between force and acceleration?

Back

According to Newton's second law, the acceleration of an object is directly proportional to the net force acting on it and inversely proportional to its mass (F=ma).

Front

What is mass?

Back

Mass is a measure of the amount of matter in an object, typically measured in kilograms.

Front

What is Newton's first law of motion?

Back

An object at rest will remain at rest, and an object in motion will continue in motion with the same speed and in the same direction unless acted upon by a net external force.

Front

What is Newton's second law of motion?

Back

Newton's second law states that the acceleration of an object is equal to the net force acting on it divided by its mass (F=ma).

Front

What is Newton's third law of motion?

Back

For every action, there is an equal and opposite reaction.
