Forces Acting on Objects- Diagram Practice

Front

What is terminal velocity?

Back

Terminal velocity is the constant speed that a freely falling object eventually reaches when the resistance of the medium (like air) prevents further acceleration.

Front

What forces act on a skydiver reaching terminal velocity?

Back

The forces acting on a skydiver are gravity (downward force) and air resistance (upward force). At terminal velocity, these forces are balanced.

Front

What is friction?

Back

Friction is a force that opposes the motion of an object. It acts parallel to the surfaces in contact.

Front

What happens when a force is applied to an object but it does not move?

Back

If a force is applied but the object does not move, it means that the applied force is less than the opposing forces (like friction) acting on the object.

Front

What is acceleration?

Back

Acceleration is the rate of change of velocity of an object. It occurs when an object speeds up, slows down, or changes direction.

Front

What is the role of gravity in free fall?

Back

Gravity is the force that pulls objects toward the Earth, causing them to accelerate downwards when in free fall.

Front

What is the difference between mass and weight?

Back

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

Front

What is Newton's First Law of Motion?

Back

Newton's First Law states that an object at rest will stay at rest, and an object in motion will stay in motion at a constant velocity unless acted upon by a net external force.

Front

What is the effect of road friction on a car's acceleration?

Back

Road friction opposes the motion of the car. It reduces the net force acting on the car, which can decrease its acceleration.

Front

What is a free-body diagram?

Back

A free-body diagram is a graphical representation used to visualize the forces acting on an object.
