What is the name of the state or condition of an object that has zero net force acting on it?

Back

Equilibrium: A state where all forces acting on an object are balanced, resulting in no acceleration.

Front

If a 10 kilogram object accelerates suddenly at 15 m/s², how much force was applied to the object?

Back

150 Newtons: Calculated using Newton's second law (F = m * a).

Front

A force of 90N is applied to each cart below, which one will accelerate the fastest?

Back

The cart with the least mass will accelerate the fastest when the same force is applied.

Front

If a force is moving a cart and suddenly a load is dumped into the cart so that the cart’s mass doubles, what happens to the cart’s acceleration?

Back

It halves: According to the formula a = F/m, if mass increases, acceleration decreases.

Front

If the net force on an object is doubled, what happens to the object's acceleration?

Back

It doubles: According to Newton's second law, acceleration is directly proportional to net force.

Front

What is Newton's second law of motion?

Back

Newton's second law 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

Define net force.

Back

Net force is the vector sum of all the forces acting on an object, determining its acceleration.

Front

What happens to an object's motion if the net force acting on it is zero?

Back

The object remains at rest or continues to move at a constant velocity (Newton's first law).

Front

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

Back

Newton (N): The force required to accelerate a 1 kg mass by 1 m/s².

Front

How does mass affect acceleration when a constant force is applied?

Back

As mass increases, acceleration decreases when the same force is applied (a = F/m).
