Define 'terminal velocity'
State what happened at point X on the graph.
Define acceleration.
State the independent variable in an experiment to determine how weight of a falling object affects terminal velocity.
Convert 3400m to km.
Challenge: Calculate the time taken for a train to accelerate from 60m/s to 64m/s, if the acceleration is 3m/s2.
State Newton’s First Law of Motion.
State what happens when a vehicle travels at a steady speed.
Explain why the velocity of an object changes.
State Newton’s First Law of Motion.
State what happens when a vehicle travels at a steady speed.
Explain why the velocity of an object changes.
What does the force of the racket do to the tennis ball?
The ball is hit harder. What does the force of the racket do to the ball now?
Which os the objects below will accelerate?
A car is travelling at a steady velocity of 7m/s to the right. Explain what happens to the car when the friction increases.
A car is stationary. When the engine is turned on and the accelerator peddle pushed down there is a greater forwards force from the thrust of the engine. Explain what will happen to the motion of the car.
A boat is travelling at a constant speed. Explain why using what you know about Newton’s First Law of Motion.
A tennis ball is travelling at a constant velocity. When it hits the tennis racket it changes direction. Explain why.
The first law of motion states that objects will remain in the same state of motion if what remains the zero?
What will happen to a stationary object if the resultant force remains zero?
What will happen to an object moving at a constant speed if the resultant force remains zero?
What will happen to an object travelling at a steady speed if the resultant force increases forwards?
What will happen to an object travelling at a steady speed if the resultant force increases backwards?
