Physics Final S1 Review 3

Front

What is net force?

Back

Net force is the vector sum of all the forces acting on an object. It determines the object's acceleration according to Newton's second law.

Front

What is the relationship between horizontal and vertical components of projectile motion?

Back

The horizontal and vertical components of projectile motion are independent of each other.

Front

What is centripetal acceleration?

Back

Centripetal acceleration is the acceleration directed towards the center of a circular path, necessary for an object to maintain circular motion.

Front

How does linear velocity vary with distance from the center of rotation?

Back

Linear velocity increases with distance from the center of rotation; the horse furthest from the center has the highest linear velocity.

Front

What is the formula to calculate mass using net force and acceleration?

Back

Mass (m) can be calculated using the formula: m = F/a, where F is the net force and a is the acceleration.

Front

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

Back

The unit of force is the Newton (N).

Front

What does it mean for forces to be balanced?

Back

Balanced forces occur when the net force acting on an object is zero, resulting in no change in motion.

Front

What is the principle of independence of motion?

Back

The principle states that the motion in one direction does not affect the motion in another direction.

Front

What is the significance of a vector in physics?

Back

A vector is a quantity that has both magnitude and direction, essential for describing forces, velocity, and acceleration.

Front

What is the difference between speed and velocity?

Back

Speed is a scalar quantity representing how fast an object moves, while velocity is a vector quantity that includes direction.
