Forces-Conceptual Physics

Front

What is the attraction between two objects because of their mass?

Back

Gravity is the force that attracts two bodies towards each other due to their mass.

Front

What is the force that is applied to an object to move it?

Back

Applied Force is the force that is applied to an object by a person or another object.

Front

What changes when you travel to another planet: your mass or your weight?

Back

Weight changes because it is dependent on the gravitational pull of the planet, while mass remains constant.

Front

True or False: The rougher the surface, the faster an object will travel over the surface.

Back

False. A rougher surface creates more friction, slowing down the object.

Front

What is the overall force acting on an object after all forces are combined?

Back

Net Force is the total force acting on an object when all individual forces are combined.

Front

What is the force that opposes the motion of an object sliding over a surface?

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 exerted by a surface to support the weight of an object resting on it?

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 pulls objects toward the center of the Earth?

Back

Weight is the force exerted on an object due to gravity, calculated as mass times the acceleration due to gravity.

Front

What is the tendency of an object to resist changes in its state of motion?

Back

Inertia is the property of matter that causes it to resist changes in its state of motion.

Front

What is the force that acts on an object moving through a fluid?

Back

Drag is the resistance force experienced by an object moving through a fluid, such as air or water.
