Use the Force (Vocab)
A push or pull that can change the motion of an object.
What is FORCE?
What is HOW FAST AN OBJECT IS MOVING?
TRUE OR FALSE
Objects with more mass experience a greater change in velocity than less massive objects when a force is applied in a certain direction.
What is FALSE?
Objects with more mass experience a greater change in velocity than less massive objects when a force is applied in a certain direction.
If two carts have different masses and the same force is applied, which changes velocity more?
What is the ONE WITH LESS MASS?
What is the formula for speed?
What is SPEED = DISTANCE ÷ TIME?
The amount of matter that makes up an object.
What is MASS?
What happens when a stronger force is applied to an object?
What is a GREATER CHANGE IN VELOCITY?
TRUE OR FALSE
A force always causes a change in an object's motion.
What is TRUE?
A light ball and heavy ball are rolled with same force. What happens to the change in velocity of the objects?
What is THE LIGHT BALL HAS A GREATER CHANGE IN VELOCITY? (LESS MASS)
What is THE HEAVY BALL HAS A SMALLER CHANGE IN VELOCITY? (MORE MASS)
A ball rolls 24 cm in 6 seconds to the northeast. What is the speed of the ball?
What is 4cm/s?
How far an object has travelled.
What is DISTANCE?
Two objects are pushed with equal force. Object A is more massive than Object B. Which will have a greater change in velocity?
What is OBJECT B?
TRUE OR FALSE.
It doesn't matter how hard you push two objects with the same mass; the change in velocity will be the same.
What is FALSE?
It depends on the strength of the force. A weaker force will have a different effect than a stronger one.
Ms. Moore says heavier objects always move slower. Is this true?
It depends on the strength of the force exerted.
The mass of Cart A is 15 kg. The mass of Cart B is 5 kg. The same force is exerted to the carts towards the left on a flat sidewalk. Which accelerates more? Why?
What is CART B? What is IT HAS LESS MASS?
How fast an object is moving in a specific direction.
What is VELOCITY?
Why are lightweight materials used on racing wheelchairs?
What is CAUSES A GREATER CHANGE IN VELOCITY BECAUSE IT HAS LESS MASS?
TRUE OR FALSE
More mass would allow a rugby wheelchair to have a greater change in velocity.
What is FALSE?
More mass would allow a rugby wheelchair to be more stable and prevent it from tipping over.
If an object's velocity increases when pushed harder, what relationship does this show between force and velocity?
What is A STRONGER FORCE CAUSES A GREATER CHANGE IN VELOCITY?
What does a weaker force do to an object's velocity?
What is IT DECREASES THE CHANGE IN VELOCITY?
This is calculated by dividing the distance an object travelled by the time it took to travel that distance.
What is SPEED?
What thought process helps you figure out what causes a change in an object's change?
What is CAUSE & EFFECT?
TRUE OR FALSE
A harder kick would make a soccer ball go faster.
What is TRUE?
Why is direction of force important in an object's velocity?
What is IT DETERMINES THE CHANGE IN VELOCITY OF AN OBJECT?
Three trials were conducted on wagons with the same mass. The following data shows the different strength of the forces exerted and the velocities calculated with each force.
Trial 1: weak force = 1 cm/s south
Trial 2: medium force = 3 cm/s south
Trial 3: strong force = 5 cm/s south.
In the data, how does force strength affect change in velocity? In other words, what is the relationship between the strength of the force and the velocity of each trial?
What is AS FORCE STRENGTH INCREASES, CHANGE IN VELOCITY ALSO INCREASES?
