Front

What is the SI unit used to measure force?

Back

newtons

Front

As the distance between two magnets is decreased, what happens to the force between them?

Back

The force increases.

Front

Why do an apple and a basketball hit the ground at the same time when dropped from a height?

Back

The force of gravity on them is equal.

Front

Where is the magnetic field strongest when using iron filings and bar magnets?

Back

The magnetic field is strongest at the magnet’s poles.

Front

If the mass of an object is doubled, what happens to the force of gravitation?

Back

The force of gravitation is doubled.

Front

What is a non-contact force?

Back

A force that acts on an object without physical contact, such as gravitational, magnetic, or electrostatic forces.

Front

What is gravitational force?

Back

The force of attraction between two masses.

Front

What is magnetic force?

Back

The force exerted by magnets when they attract or repel each other.

Front

What is electrostatic force?

Back

The force between charged objects, which can be attractive or repulsive.

Front

How does distance affect gravitational force?

Back

Gravitational force decreases as the distance between two objects increases.
