FIZIX1st Sem Review - Forces

Front

What is the net force on an object at rest?

Back

0 N

Front

How do you calculate acceleration using Newton's second law?

Back

Acceleration (a) = Net Force (∑F) / Mass (m)

Front

What is mass?

Back

The amount of inertia an object has.

Front

What does Newton's second law state?

Back

∑F = m * a

Front

If two wagons are pulled with the same force, how does their mass affect their acceleration?

Back

The wagon with less mass will have greater acceleration.

Front

What is inertia?

Back

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

Front

What is weight?

Back

The force of gravity acting on an object, calculated as weight (W) = mass (m) * gravity (g).

Front

How does gravity affect weight?

Back

Weight increases with greater mass and stronger gravitational pull.

Front

What is the formula for calculating weight?

Back

W = m * g, where g is the acceleration due to gravity (approximately 9.8 m/s² on Earth).

Front

What is the relationship between force, mass, and acceleration?

Back

Force is directly proportional to mass and acceleration (F = m * a).
