Forces practice test questions

Front

What is gravitational attraction?

Back

Gravitational attraction is the force that pulls two objects toward each other, depending on their masses and the distance between them.

Front

What two factors affect the magnitude of the force of gravity between two objects?

Back

Mass and distance.

Front

What is inertia?

Back

Inertia is the resistance of an object to change its state of motion; the greater the mass, the greater the inertia.

Front

What does it mean for forces to be in equilibrium?

Back

Forces are in equilibrium when they are equal in magnitude and opposite in direction, resulting in no net force acting on the object.

Front

How does pulling up on an object while pushing it affect friction?

Back

Pulling up decreases the normal force, which reduces the friction acting against the motion of the object.

Front

What is the relationship between mass and gravitational force?

Back

The gravitational force increases with greater mass; more massive objects exert a stronger gravitational pull.

Front

How does distance affect gravitational attraction?

Back

Gravitational attraction decreases as the distance between two objects increases.

Front

What is the difference between weight and mass?

Back

Mass is the amount of matter in an object, while weight is the force of gravity acting on that mass.

Front

What is normal force?

Back

Normal force is the support force exerted by a surface perpendicular to the object resting on it.

Front

What happens to an object in motion when no net force acts on it?

Back

An object in motion will continue to move at a constant velocity if no net force acts on it.
