What is velocity?

Back

Velocity is the speed of an object in a specific direction, measured in units such as meters per second (m/s). For example, 10 m/s north is a velocity.

Front

What is net force?

Back

Net force is the total force acting on an object after all the forces are combined. It determines the object's acceleration and direction.

Front

What is a balanced force?

Back

Balanced forces occur when two forces acting on an object are equal in size but opposite in direction, resulting in no change in motion.

Front

What are the three states of matter?

Back

The three states of matter are solid, liquid, and gas. Each state has distinct properties and behaviors.

Front

What happens to the charge of a plastic rod when rubbed with wool?

Back

When a plastic rod is rubbed with wool, electrons are transferred from the wool to the rod, giving the rod a negative charge.

Front

What is acceleration?

Back

Acceleration is the rate of change of velocity of an object. It occurs when an object speeds up, slows down, or changes direction.

Front

What is the formula for calculating acceleration?

Back

Acceleration (a) can be calculated using the formula: a = (final velocity - initial velocity) / time.

Front

What is the difference between speed and velocity?

Back

Speed is a scalar quantity that refers to how fast an object is moving, while velocity is a vector quantity that includes both speed and direction.

Front

What is an example of an unbalanced force?

Back

An example of an unbalanced force is when a 10 N force pushes an object to the right and a 4 N force pushes it to the left, resulting in a net force of 6 N to the right.

Front

What is the definition of a solid?

Back

A solid is a state of matter characterized by a definite shape and volume, with particles that are closely packed together.
