Linear Motion

Front

What is the principle of inertia in linear motion?

Back

The principle of inertia states that an object at rest will remain at rest, and an object in motion will remain in motion at a constant velocity unless acted upon by a net external force.

Front

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

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 (F = ma).

Front

What is the effect of wind resistance on falling objects?

Back

Wind resistance, or air resistance, opposes the motion of an object moving through the air, causing lighter objects like feathers to fall slower than heavier objects like bowling balls.

Front

How does changing direction affect velocity?

Back

Velocity is a vector quantity that includes both speed and direction; therefore, changing direction while maintaining speed results in a change in velocity.

Front

What is the definition of acceleration?

Back

Acceleration is the rate of change of velocity of an object with respect to time.

Front

What factors affect the acceleration of an object?

Back

The acceleration of an object is affected by the net force acting on it and its mass.

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 happens to the motion of an object when no net force is acting on it?

Back

When no net force is acting on an object, it will either remain at rest or continue to move at a constant velocity.

Front

What is the significance of a changing velocity in terms of motion?

Back

A changing velocity indicates that an object is either accelerating or decelerating, which means there is a net force acting on it.

Front

How does mass affect the acceleration of an object when a constant force is applied?

Back

When a constant force is applied, an object with greater mass will experience less acceleration compared to an object with less mass, according to Newton's second law.
