What is an electromagnet?

Back

An electromagnet is a type of magnet in which the magnetic field is produced by an electric current. It typically consists of a solid iron core wrapped in wire, which is connected to a battery.

What is a dependent variable in an experiment?

Back

The dependent variable is the variable that is measured or observed in an experiment. It is affected by changes in the independent variable.

What is the relationship between mass and height in projectile motion?

Back

In projectile motion, as the mass of an object increases, the maximum height it can reach decreases when the same amount of force is applied.

What causes tides in Earth's oceans?

Back

Tides are caused by the gravitational forces exerted by the Moon and the Sun on Earth, leading to changes in the tidal bulge of the oceans.

What is the role of force in motion?

Back

Force is a push or pull that can cause an object to move, change its velocity, or stop moving. The direction and magnitude of the force affect the motion of the object.

What is the effect of applying force on an object?

Back

Applying force to an object can change its state of motion, causing it to accelerate, decelerate, or change direction.

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.
