Physics - 2D Vectors (1)

Front

What is a vector?

Back

A vector is a quantity that has both magnitude and direction, such as force, velocity, and displacement.

Front

What is the equilibrant force?

Back

The equilibrant force is the force that balances out other forces acting on an object, making the net force zero.

Front

How do you determine the direction of the equilibrant force?

Back

The equilibrant force acts in the opposite direction to the resultant force.

Front

What is the normal force?

Back

The normal force is the force exerted by a surface to support the weight of an object resting on it, acting perpendicular to the surface.

Front

How do you calculate the perpendicular component of a force on an incline?

Back

The perpendicular component can be calculated using the formula: F_perpendicular = F * cos(θ), where F is the force and θ is the angle of the incline.

Front

What is the formula for calculating the force of friction?

Back

The force of friction can be calculated using the formula: F_friction = μ * N, where μ is the coefficient of friction and N is the normal force.

Front

What is the significance of the angle in vector problems?

Back

The angle in vector problems determines the direction of the vector and is crucial for resolving vectors into their components.

Front

What is the difference between static and kinetic friction?

Back

Static friction acts on an object at rest and prevents it from moving, while kinetic friction acts on an object in motion.

Front

How do you resolve a vector into its components?

Back

To resolve a vector into its components, use trigonometric functions: F_x = F * cos(θ) and F_y = F * sin(θ).

Front

What is the relationship between mass and weight?

Back

Weight is the force exerted by gravity on an object and is calculated as W = m * g, where m is mass and g is the acceleration due to gravity.
