Front

What is tension in a string?

Back

Tension is the force exerted along the length of a string, rope, or cable when it is pulled tight by forces acting from opposite ends.

Front

How do you calculate the mass of an object using tension?

Back

Mass can be calculated using the formula: mass = tension / gravitational acceleration (g = 9.81 m/s²).

Front

What factors affect the acceleration of an object on an incline?

Back

The acceleration of an object on an incline is affected by the angle of the incline, the mass of the object, and the gravitational force acting on it.

Front

What is the relationship between weight and acceleration on an incline?

Back

The component of weight acting down the incline determines the net force and thus the acceleration of the object.

Front

What is the formula for net force acting on an object?

Back

Net force (F_net) is calculated using Newton's second law: F_net = mass (m) × acceleration (a).

Front

What is the significance of neglecting friction and drag in physics problems?

Back

Neglecting friction and drag simplifies calculations, allowing focus on the primary forces acting on the object.

Front

How does the slope of a ramp affect the acceleration of a cart?

Back

A steeper slope increases the component of gravitational force acting down the ramp, resulting in greater acceleration.

Front

What is gravitational force?

Back

Gravitational force is the attractive force between two masses, calculated using the formula: F_gravity = mass (m) × gravitational acceleration (g).

Front

What is the role of normal force on an incline?

Back

Normal force is the perpendicular force exerted by a surface to support the weight of an object resting on it, affecting the object's motion.

Front

What is the difference between weight and mass?

Back

Weight is the force exerted by gravity on an object (W = m × g), while mass is the amount of matter in an object, measured in kilograms.
