Newton's Laws

What does Newton's First Law of Motion describe?

• The relationship between force, mass, and acceleration.

• The tendency of an object to resist changes in its state of motion.

• The principle that for every action, there is an equal and opposite reaction.

• The force of gravity acting on an object.

If two objects of the same size are compared, which one would have more inertia?

• The object with less mass.

• The object with more mass.

• The object that is moving faster.

• The object that is at rest.

What happens to an object when the forces acting on it are unbalanced?

• It remains at rest.

• It moves at a constant velocity.

• It experiences acceleration.

• It enters a state of equilibrium.

What is a key characteristic of the normal force?

• It is always equal to the force of gravity.

• It always points downwards.

• It is always perpendicular to the surface an object is resting on.

• It is only present when an object is in motion.

What is the primary purpose of drawing a free body diagram?

• To determine the object's color.

• To visualize all forces acting on an object.

• To calculate the object's volume.

• To measure the object's temperature.

If an object is at rest or moving at a constant velocity, what is the net force acting on it?

• Greater than zero

• Less than zero

• Equal to zero

• Cannot be determined

What type of force acts upwards on a box resting on the ground, and what type of force acts upwards on a box suspended by a rope?

• Friction force, Air resistance

• Normal force, Tension force

• Applied force, Gravitational force

• Magnetic force, Electrical force

An elevator with a mass of 1000 kg is connected to a counterweight of 850 kg via a pulley system. If the system is released, what will be the direction of the elevator's acceleration?

• Upward

• Downward

• No acceleration

• Sideways
