What is mass?

Back

Mass is a measure of the amount of matter in an object, typically measured in kilograms (kg). It determines how much force is needed to change the object's motion.

Front

What is velocity?

Back

Velocity is the speed of an object in a specific direction, expressed in meters per second (m/s). It includes both the magnitude (speed) and the direction of motion.

Front

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

Back

When a constant force is applied, an object with greater mass will experience a smaller change in velocity compared to an object with less mass.

Front

What happens to the velocity of an object if its mass is decreased while the force remains constant?

Back

If the mass of an object is decreased while the force remains constant, the object will experience a greater change in velocity.

Front

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

Back

According to Newton's second law, the relationship is defined by the formula: Force = Mass x Acceleration (F = m x a). This means that for a given force, acceleration is inversely proportional to mass.

Front

What is inertia?

Back

Inertia is the tendency of an object to resist changes in its state of motion. An object with more mass has more inertia.

Front

What is the effect of increasing force on the velocity of an object?

Back

Increasing the force applied to an object will result in a greater change in its velocity, assuming mass remains constant.

Front

What is the difference between speed and velocity?

Back

Speed is a scalar quantity that refers to how fast an object is moving, while velocity is a vector quantity that includes both speed and direction.

Front

What is the formula for calculating velocity?

Back

Velocity (v) can be calculated using the formula: v = distance (d) / time (t).

Front

How does changing the direction of force affect motion?

Back

Changing the direction of the force applied to an object will change the direction of its motion, affecting its velocity.
