PS2.A Flashcard

Front

Which factor affects the friction force between two surfaces?

Back

The type of surface material.

Front

What is the unit of force in the International System of Units (SI)?

Back

Newton (N).

Front

What is the centripetal force acting on an object in circular motion?

Back

The force directed towards the center of the circular path.

Front

A ball is thrown horizontally. Which force causes it to fall to the ground?

Back

Gravity.

Front

What is the effect of doubling the mass of an object on its acceleration when a constant force is applied?

Back

The acceleration is halved.

Front

Define friction force.

Back

The force that opposes the relative motion of two surfaces in contact.

Front

What is the formula for calculating force?

Back

Force = Mass × Acceleration (F = ma).

Front

Explain centripetal acceleration.

Back

The acceleration of an object moving in a circular path, directed towards the center of the circle.

Front

What is inertia?

Back

The tendency of an object to resist changes in its state of motion.

Front

What is the relationship between mass and weight?

Back

Weight is the force exerted by gravity on an object, calculated as Weight = Mass × Gravitational Acceleration.
