Front

What is Newton's First 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

Define balanced forces.

Back

Balanced forces are two or more forces acting on an object that cancel each other out, resulting in no net force and no change in motion.

Front

What is an unbalanced force?

Back

An unbalanced force occurs when the total force acting on an object is not zero, causing the object to accelerate in the direction of the net force.

Front

How do you determine the net force acting on an object?

Back

The net force is determined by adding all the forces acting on an object, taking into account their directions.

Front

What is acceleration?

Back

Acceleration is the rate of change of velocity of an object, which can be caused by a change in speed or direction.

Front

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

Back

According to Newton's Second Law, the force acting on an object is equal to the mass of the object multiplied by its acceleration (F = ma).

Front

What happens to an object when the forces acting on it are balanced?

Back

When forces are balanced, the object will either remain at rest or continue to move at a constant velocity.

Front

What is the effect of gravity on objects?

Back

Gravity is a force that pulls objects toward the center of the Earth, giving them weight.

Front

How does friction affect motion?

Back

Friction is a force that opposes motion between two surfaces in contact, which can slow down or stop moving objects.

Front

What is the significance of the force applied to a train?

Back

The force applied to a train determines its acceleration and the number of cars it can pull, affecting its overall performance.
