Newtons Laws 24-25

Front

What is Newton's 1st Law of Motion?

Back

An object at rest stays at rest, and an object in motion stays in motion with the same speed and in the same direction unless acted upon by an unbalanced force.

Front

What is Newton's 2nd Law of Motion?

Back

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 Newton's 3rd Law of Motion?

Back

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

Front

Define 'mass'.

Back

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

Front

Define 'weight'.

Back

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

Front

What is 'gravity'?

Back

Gravity is the attractive force that exists between all objects that have mass.

Front

What is a 'balanced force'?

Back

Balanced forces are equal in size and opposite in direction, resulting in no change in motion.

Front

What is an 'unbalanced force'?

Back

Unbalanced forces are not equal and can cause an object to accelerate or change its motion.

Front

What is 'tension force'?

Back

Tension force is the force transmitted through a string, rope, or cable when it is pulled tight by forces acting from opposite ends.

Front

What is the formula to calculate force?

Back

Force (F) is calculated using the formula F = ma, where 'm' is mass and 'a' is acceleration.
