Forces on Objects Test

Front

What is an applied force?

Back

An applied force is a force that is applied to an object by a person or another object. For example, when Juanita's father pushes her on the swing, he is applying a force.

Front

What is friction?

Back

Friction is a force that resists the motion of two surfaces sliding across one another. It acts in the opposite direction to the motion.

Front

What is weight?

Back

Weight is the force exerted by gravity on an object. It is measured in newtons (N) and can change depending on the object's location in a gravitational field.

Front

What is normal force?

Back

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

Front

What is gravity?

Back

Gravity is a force that attracts two bodies towards each other. On Earth, it gives weight to physical objects and causes them to fall towards the ground.

Front

What is the relationship between mass and weight?

Back

Mass is the amount of matter in an object, while weight is the force of gravity acting on that mass. Weight is calculated as mass times the acceleration due to gravity.

Front

What is the net force?

Back

Net force is the overall force acting on an object when all the individual forces acting on it are combined. It determines the object's motion.

Front

What happens when forces are balanced?

Back

When forces are balanced, the net force is zero, and the object remains at rest or continues to move at a constant velocity.

Front

What happens when forces are unbalanced?

Back

When forces are unbalanced, the net force is not zero, causing the object to accelerate in the direction of the greater force.

Front

What is tension?

Back

Tension is a force that is transmitted through a string, rope, or wire when it is pulled tight by forces acting from opposite ends.
