Warm-up 15 Flashcard Forces

Front

What is gravitational force?

Back

Gravitational force is the attraction between two objects due to their mass. It pulls objects towards each other, like how the Earth pulls us down.

Front

What is an unbalanced force?

Back

An unbalanced force occurs when the total forces acting on an object are not equal, causing the object to accelerate in the direction of the greater force.

Front

Can an object with zero net force be moving?

Back

Yes, an object with zero net force can be moving at a constant speed in a straight line.

Front

What is net force?

Back

Net force is the overall force acting on an object after all the individual forces are combined.

Front

What force opposes motion when pushing a box across the floor?

Back

Friction is the force that opposes motion between two surfaces in contact.

Front

What is normal force?

Back

Normal force is the support force exerted upon an object that is in contact with another stable object, acting perpendicular to the surface.

Front

What is applied force?

Back

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

Front

What is friction?

Back

Friction is a force that resists the sliding or rolling of one surface over another.

Front

What is balanced force?

Back

Balanced forces are equal in size and opposite in direction, resulting in no change in motion.

Front

What happens when forces are balanced?

Back

When forces are balanced, the object remains at rest or continues to move at a constant velocity.
