Front

What is the vertical component of tension in a pendulum?

Back

The vertical component of tension is the force acting in the upward direction that balances the weight of the pendulum bob.

Front

How do you calculate the horizontal component of tension in a pendulum?

Back

Front

What is the formula for acceleration in a system of masses?

Back

Front

What is the direction of friction when pulling an object?

Back

Friction always acts in the opposite direction to the motion of the object.

Front

How does increasing the angle of a rope affect the tension in the rope?

Back

As the angle increases, the vertical component of tension decreases, which can affect the acceleration of the object being pulled.

Front

What is the relationship between mass and acceleration in a system?

Back

According to Newton's second law, acceleration is inversely proportional to mass when the net force is constant.

Front

Define tension in the context of forces acting on an object.

Back

Tension is the force transmitted through a string, rope, or cable when it is pulled tight by forces acting from opposite ends.

Front

What happens to the acceleration of an object if the net force acting on it is zero?

Back

If the net force is zero, the acceleration of the object is also zero, meaning it remains at rest or continues to move at a constant velocity.

Front

What is the effect of mass on the gravitational force acting on an object?

Back

Front

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

Back

The net force is the vector sum of all the forces acting on the object, taking into account their directions.
