FORCE AND MOTION

Front

What is an unbalanced force?

Back

An unbalanced force is a force that causes an object to change its state of motion, either by accelerating, decelerating, or changing direction.

Front

Define speed in the context of motion.

Back

Speed is the rate at which an object covers distance, typically measured in meters per second (m/s).

Front

What does a horizontal line on a distance-time graph indicate?

Back

A horizontal line on a distance-time graph indicates that the object is not moving.

Front

What is the definition of force?

Back

Force is a push or pull exerted on an object, which can cause it to accelerate, decelerate, or change direction.

Front

How do you calculate speed?

Back

Speed is calculated by dividing the distance traveled by the time taken (Speed = Distance / Time).

Front

What is the difference between balanced and unbalanced forces?

Back

Balanced forces are equal in size and opposite in direction, resulting in no change in motion, while unbalanced forces result in a change in motion.

Front

What is inertia?

Back

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

Front

What is the formula for calculating acceleration?

Back

Acceleration is calculated using the formula: Acceleration = (Final Velocity - Initial Velocity) / Time.

Front

What is the relationship between mass and force according to Newton's second law?

Back

According to Newton's second law, force is equal to mass times acceleration (F = m * a).

Front

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

Back

The unit of force in the SI system is the Newton (N).
