newtons laws

Front

What is the attractive force that exists between all objects that have mass?

Back

Gravity is the force that attracts two bodies towards each other, depending on their masses and the distance between them.

Front

What happens when two boys pull with the same amount of force?

Back

They will not move at all because the forces are balanced.

Front

What law is best described by inertia?

Back

The 1st Law of Motion states that an object at rest stays at rest, and an object in motion stays in motion unless acted upon by a net external force.

Front

What is the 3rd Law of Motion?

Back

The 3rd Law of Motion states that for every action, there is an equal and opposite reaction.

Front

What does 'Equal and Opposite' refer to in physics?

Back

It refers to the 3rd Law of Motion, which states that forces always occur in pairs.

Front

What is mass?

Back

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

Front

What is weight?

Back

Weight is the force exerted by gravity on an object, calculated as mass times the acceleration due to gravity (W = mg).

Front

What is the 2nd Law of Motion?

Back

The 2nd Law of Motion states that 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 inertia?

Back

Inertia is the tendency of an object to resist changes in its state of motion.

Front

What is the relationship between mass and weight?

Back

Weight is the gravitational force acting on an object's mass; weight increases with mass.
