Forces & Motion 5.P.1.1, 5.P.1.2, 5.P.1.3, and 5.P.1.4

Front

What is force?

Back

A force is a push or pull that can make an object start moving, stop moving, speed up, or slow down.

Front

What is speed?

Back

Speed is the distance an object travels in a certain amount of time.

Front

How do you calculate average speed?

Back

Average speed is calculated by dividing the total distance traveled by the total time taken.

Front

What happens to an object's motion when a force is applied in the same direction as its movement?

Back

The object will speed up.

Front

What is the effect of a force acting in the opposite direction of an object's motion?

Back

The object will slow down.

Front

What is inertia?

Back

Inertia is the tendency of an object to resist changes in its state of motion.

Front

What is the relationship between mass and force?

Back

The greater the mass of an object, the more force is needed to change its motion.

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 can cause an object to start moving, stop moving, or change direction.

Front

What is the role of friction in motion?

Back

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