Force and Motion

Front

What is the net force on an object?

Back

The net force is the total force acting on an object after all the individual forces are combined. It determines the object's acceleration and direction.

Front

What is gravity?

Back

Gravity is the force that attracts two bodies towards each other, depending on their masses and the distance between them.

Front

What is motion?

Back

Motion is the change of position of an object over time, described by its distance and direction from a reference point.

Front

How do you calculate speed?

Back

Speed is calculated using the formula: Speed = Distance / Time.

Front

What is acceleration?

Back

Acceleration is the rate of change of velocity of an object, indicating how quickly it is speeding up or slowing down.

Front

What is the difference between speed and velocity?

Back

Speed is a scalar quantity that refers to how fast an object is moving, while velocity is a vector quantity that includes both speed and direction.

Front

What is a reference point in motion?

Back

A reference point is a stationary object or location used to determine the position or motion of another object.

Front

What is the formula for calculating net force?

Back

Net Force = Mass x Acceleration (F = m*a).

Front

What is inertia?

Back

Inertia is the tendency of an object to resist changes in its state of motion, depending on its mass.

Front

What is the relationship between mass and weight?

Back

Weight is the force of gravity acting on an object's mass, calculated as Weight = Mass x Gravity.
