Front

What is Newton's second 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 tension force?

Back

The force that is transmitted through a string, rope, cable, or wire when it is pulled tight.

Front

Define mass.

Back

A measure of how much matter an object has.

Front

How do you calculate weight?

Back

Weight is calculated using the formula: Weight (W) = mass (m) × gravitational acceleration (g).

Front

What does Newton's First Law state?

Back

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 unit of force in the International System of Units (SI)?

Back

The unit of force is the Newton (N).

Front

What is gravitational force?

Back

The attractive force between two objects due to their mass.

Front

What is the relationship between mass and weight?

Back

Weight is the force exerted by gravity on an object, which depends on its mass and the acceleration due to gravity.

Front

What is the formula for calculating acceleration?

Back

Acceleration (a) = (final velocity (v) - initial velocity (u)) / time (t).

Front

What is inertia?

Back

The tendency of an object to resist changes in its state of motion.
