Putting it All Together: Force

Front

What is net force?

Back

Net force is the total force acting on an object when all the individual forces are combined. It determines the object's acceleration according to Newton's second law.

Front

What is the formula to calculate net force?

Back

Net force (F) can be calculated using the formula: F = m * a, where m is mass and a is acceleration.

Front

What is the unit of force?

Back

The unit of force is the Newton (N).

Front

What is the relationship between mass 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.

Front

What is inertia?

Back

Inertia is the tendency of an object to resist changes in its state of motion. It is directly related to the mass of the object.

Front

What is the acceleration of an object at rest?

Back

The acceleration of an object at rest is 0 m/s², meaning there is no change in its velocity.

Front

How do you calculate the weight of an object?

Back

Weight (W) can be calculated using the formula: W = m * g, where m is mass and g is the acceleration due to gravity (approximately 9.81 m/s² on Earth).

Front

What is momentum?

Back

Momentum is the product of an object's mass and its velocity, represented by the formula: p = m * v.

Front

What is the principle of conservation of momentum?

Back

The principle of conservation of momentum states that in a closed system, the total momentum before an event is equal to the total momentum after the event.

Front

What happens to the net force if multiple forces are acting in the same direction?

Back

If multiple forces act in the same direction, the net force is the sum of all the individual forces.
