Force: Friction, Gravity, and Magnetism

Front

What is the force between two surfaces that are sliding called?

Back

Friction

Front

Define gravity.

Back

Gravity is a force that attracts two bodies towards each other.

Front

What causes a kicked soccer ball to eventually stop moving?

Back

Friction between the ball and the ground.

Front

What is defined as any push or pull that causes an object to move, stop, or change speed or direction?

Back

Force

Front

On which type of surface would a ball move slowly?

Back

Carpet.

Front

What is the effect of friction on the motion of an object?

Back

Friction opposes the motion of an object, causing it to slow down or stop.

Front

What is the relationship between mass and gravitational force?

Back

The gravitational force increases with the mass of the objects involved.

Front

How does the distance between two objects affect gravitational force?

Back

The gravitational force decreases as the distance between the objects increases.

Front

What is the formula for calculating gravitational force?

Back

F = G * (m1 * m2) / r^2, where F is the gravitational force, G is the gravitational constant, m1 and m2 are the masses, and r is the distance between the centers of the two masses.

Front

What is magnetism?

Back

Magnetism is a force that can attract or repel certain materials, typically metals, due to the motion of electric charges.
