Forces and Motion

Front

What is the relationship between force and motion in physics?

Back

Force is a push or pull that can cause an object to accelerate, change direction, or change shape. Motion is the change in position of an object over time, which can be influenced by the forces acting on it.

What is the formula for calculating force?

Back

Force (F) is calculated using the formula F = m * a, where m is mass and a is acceleration.

What is friction and how does it affect motion?

Back

Friction is a force that opposes the motion of an object. It can slow down or stop moving objects and is affected by the surfaces in contact and the force pressing them together.

What is magnetism and how does it relate to forces?

Back

Magnetism is a noncontact force that attracts certain metals, such as iron, and is caused by the motion of electric charges.

How does mass affect the distance an object will move when pushed with the same force?

Back

When two objects are pushed with the same force, the one with less mass will accelerate more and typically move a longer distance.

What is the effect of lubrication on machine parts?

Back

Lubrication, such as oil, reduces friction between machine parts, allowing them to move more freely and operate more efficiently.

Front

What is the role of gravity in motion?

Back

Gravity is a force that attracts objects toward each other, most notably the attraction between the Earth and objects near its surface, affecting their motion.

What is the difference between contact and noncontact forces?

Back

Contact forces require physical contact between objects (e.g., friction, tension), while noncontact forces act at a distance (e.g., gravity, magnetism).

Front

How can increasing force affect the motion of an object?

Back

Increasing the force applied to an object will increase its acceleration, allowing it to move faster or further.

What are the factors that affect friction?

Back

Friction is affected by the types of surfaces in contact, the roughness of those surfaces, and the amount of force pressing them together.
