What is gravitational influence?

Back

Gravitational influence refers to the effect that a mass has on the gravitational field around it, affecting the motion of other masses. The strength of this influence decreases with distance.

Front

How does distance affect gravitational influence?

Back

The gravitational influence of an object decreases as the distance from that object increases. For example, the gravitational pull of distant stars is negligible compared to that of nearby objects like the Sun.

Front

What is speed in physics?

Back

Speed is the distance traveled per unit of time, typically measured in meters per second (m/s). It indicates how fast an object is moving.

Front

What does it mean for speed to increase?

Back

When the speed of an object increases, it means that the object is covering more distance in the same amount of time, indicating acceleration.

Front

What is momentum?

Back

Momentum is the product of an object's mass and its velocity, represented by the formula p = mv. It is a vector quantity, meaning it has both magnitude and direction.

Front

What happens to momentum when velocity decreases?

Back

When the velocity of an object decreases, its momentum also decreases, as momentum is directly proportional to velocity.

Front

What is net force?

Back

Net force is the total force acting on an object after all the individual forces are combined. It determines the object's acceleration according to Newton's second law.

Front

How do you calculate net force?

Back

Net force is calculated by subtracting opposing forces from each other. For example, if an object is pulled with 10 N up and 15 N down, the net force is 5 N down.

Front

What is displacement?

Back

Displacement is the shortest distance from the initial to the final position of an object, including direction. It is a vector quantity.

Front

What is distance in physics?

Back

Distance is the total length of the path traveled by an object, regardless of direction. It is a scalar quantity.
