Force and Motion

Front

What is the overall speed of an object during the entire course of a trip?

Back

Average speed is the total distance traveled divided by the total time taken.

Front

What force do objects exert on each other because of their masses?

Back

Gravity is the force that attracts two bodies towards each other.

Front

What is net force?

Back

Net force is the total force acting on an object, taking into account all the individual forces acting on it.

Front

How do you calculate average speed?

Back

Average speed is calculated using the formula S = d/t, where S is speed, d is distance, and t is time.

Front

What is friction?

Back

Friction is a force that resists the motion of two surfaces sliding against each other.

Front

What is the unit of force?

Back

The unit of force is the Newton (N).

Front

What is acceleration?

Back

Acceleration is the rate of change of velocity of an object.

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 balanced force?

Back

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

Front

What is an unbalanced force?

Back

Unbalanced forces are not equal and opposite, causing a change in the motion of an object.
