Newton & Laws

Front

What is inertia?

Back

Inertia is the tendency of an object to resist changes in its motion. It means that an object at rest stays at rest, and an object in motion stays in motion unless acted upon by a force.

What is a Newton?

Back

A Newton (N) is the unit of force in the International System of Units (SI). It is defined as the amount of force required to accelerate a one-kilogram mass by one meter per second squared.

Front

What is net force?

Back

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 is a force?

Back

A force is any push or pull on an object. Forces can cause an object to start moving, stop moving, or change direction.

Front

What does it mean for forces to be balanced?

Back

Balanced forces occur when two forces acting on an object are equal in size but opposite in direction, resulting in no change in motion.

Front

What is acceleration?

Back

Acceleration is the rate at which an object changes its velocity. It can be a change in speed or direction.

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. It is a scalar quantity and does not change regardless of location.

Front

What is the difference between mass and weight?

Back

Mass is the amount of matter in an object, while weight is the force exerted by gravity on that mass. Weight can change depending on the gravitational field.

Front

What is friction?

Back

Friction is a force that opposes the motion of an object. It occurs when two surfaces come into contact and can slow down or stop the movement.
