Force and Motion Review (2024)

Front

What is the total amount of force acting on an object?

Back

Net force is the total amount of force acting on an object, taking into account both the magnitude and direction of all individual forces.

Front

What is the net force when all forces acting on an object are balanced?

Back

0 N (zero net force indicates that the object is either at rest or moving at a constant velocity).

Front

What type of force is exerted when objects are not touching?

Back

Non-contact force is a force that acts on an object without physical contact, such as gravitational force.

Front

What is the reaction force when a skateboarder pushes off the ground backward?

Back

The skateboard rolls forward as a reaction to the skateboarder pushing off the ground.

Front

What is the force that acts perpendicular to the surface an object is resting on?

Back

Normal force is the support force exerted upon an object that is in contact with another stable object.

Front

What is the force that opposes the motion of an object?

Back

Friction is the force that opposes the relative motion of solid surfaces, fluid layers, and material elements sliding against each other.

Front

What is the force that pulls objects toward the center of the Earth?

Back

Gravity is the force that attracts two bodies toward each other, commonly experienced as the force that pulls objects toward the Earth.

Front

What is the difference between balanced and unbalanced forces?

Back

Balanced forces result in no change in motion, while unbalanced forces cause an object to accelerate.

Front

What is the formula for calculating force?

Back

Force (F) = mass (m) × acceleration (a).

Front

What is inertia?

Back

Inertia is the tendency of an object to resist changes in its state of motion.
